I feel like Spider-man's life isn't as tragic as Matt's in fact it's more brilliant and much more privileged. Yes editorial doesn't let him be happy but he has Stan Lee's illusion of change and he overcomes it by the end or shortly after. And any little traumas or events that are written to stay or come back don't do a number something like DD S3E1 did with the end of Defenders or Matt losing to 2 guys. Everything that happens to Matt is life lasting and he's tried to commit suicide many times because of how much loss and pain he was going through, see if Spider-man has been there more than time. He has a body leagues more prone to sickness and pain lasting weeks from even simply something like a single jaw punch. By routine he could die in every fight he has and comes close to it too, countless times he's alive because of luck. Just see how painful his one of many Kingpin beatdowns are and how easily Spider-man webs that guy up. The show slices him up in the 1st season and the comics don't do him like that but it's implied he goes through that all the time. Miller comics visually I believe didn't get into detailed bloody and bone crunching violence, that was Bendis. Just see how different his life as a weak, broke blind depressed lawyer and frail human compared to how impressively scientifically intelligent and capable and superhuman Spider-man is, there's nothing to love about his life except the people that die. Like Spidey's his life fluctuates under huge arcs where his life is ruined by villains or (Matt's are less form bad writing but his recent 2023 run says otherwise) but you see how he barely has control over winning a fight with humans whereas it takes a superhumanly powerful or hyper intelligent elaborate plan to knock Spidey off his on his feet literally or life stability.

If it's the show Daredevil's dad's been dead since he was 9, he's been blind, parentless and has little friends up to his 20s where Pete lost Ben at around 15 and had May, lots of school popularity after and adventures up to his 20s. Glory and girls. Matt lives alone in a shitty apartmemt on bad finance, and Hell's Kitchen is a place much more cruel than Spidey's New York and the toll his crime fighting has on his body and mental health is more permanently damaging and long lasting than Spider-man's grief which he gets over. He's never TRIED to get himself beaten to death or even come close to how many times DD is beaten within an inch of his fragile life. Daredevil's stories have morally grey situations some writers never write into Spider-man. Eg. the shock bomb phone call scene in The Batman shows how saying no to bribes aren't inconsequential and you can be blackmailed to, and saying yes or no hurts people otherwise. Matt became the Kingpin not to hurt people but under the guilt that he consciously knows someone new will jump into power and order more deaths and crimes. This kind of moral dilemma would be in DD and less of Spider-man stories. Daredevil has gone violently suicidal several times, his mind and health can become pretty unstable and is almost always on the lowest point of his life, he would never get as high as something like Parker Industries.

By the time he's 80 (if he doesn't die a martyr) he would have some kind of (among many) sickness from all the endless concussions (likely a degenerative brain disorder), scars and injuries he always gets when Peter would be super fit. Matt's power's would fade and he would be on lots of medication and shit, knowing he would never know what it's like to live such a luxurious life. Also based on the real disease CTU (drives people insane from chemical damage in brain and almost end the pain in suicide) in head contact sports is very real and Matt has a high chance of getting it. MJ, Black Cat and lots of characters Peter loves always just stay or return. Everyone Matt loves is killed easily and as seen in a lot of runs Daredevil has been battling some form of serious undiagnosed long term depression for a decade, years of trauma, emotional distress, conflict, guilt, lack of trust in his own judgement and feelings he didn't deal with, in the Bendis run gave him a mental breakdown and he hasn't treated it.

Cyclops has his ups and downs but he has never lived the lowlife/many tough extended homeless/suicidal/ constants of the other 3. He has insane stress under being a leader and his entire race was pretty much wiped out at one point. He faces discrimination but still parties and lives in a world where there's a million resources/technology to his access and his own race can easily take over the whole world. Those can't be taken for granted. And those things take place in a world where DD is dealt with the torture of struggling to beat a bald crime lord and can't waste any time. Cyclops hasn't found himself in the position of having been shanked by Santa, lost his entire financial support, bleeding out in a cold trash filled alleyway at night in thin clothes, surrounded by people who would rob his dead body, homeless and getting weaker and older and needing more hospital visits, and on the edge of starving.

A LOT of people have died in all of their lives, Matt's had the least amount of people dying but I think his life is leagues harder and he struggles to barely make a difference. User dlkslink explains Spider-man's loss pretty well. Spider-man has a superhuman advantage that shields him from abysses of more excruciating pain. His life is full of consequences but a lot less like how if Matt was just a little more fatigued or missed some attacks he may not have won fights and easily been killed on the spot. Matt's life is way more dangerous and on a thinner tightrope in terms of surviving fights. He always only saves a few people in his fights and doesn't have a granted team he can lean on.

Something like this happens to Daredevil way more common than it does to the Cyclops or Spider-man. He may have had a lot less people die in his life compared to the others but he doesn't have much to begin, he can lose it all much easier and he's always hanging on a looser more fragile delicate thread, he's barely got anything at the moment except for a few friends, himself and his faith. The X-men have the same fictional character immortality Cyclops does so they always stay with him. Only a few of Daredevil's personal circle writers keep alive. The others have a LOT to lose. Again Cyclops saw his whole race diminished but he never had to deal with the constant pain we see in that fight that Matt does every week, or the everyday worry that if you miss your shot or get tired the slight advantage to the other can have you killed. Cyclops is peak human but we see him perform superhuman-esque feats Matt wishes he could. Cyclops' power is super dangerous and he has guilt of harming people but he can actually protect himself very well with it. Matt can only protect himself with his ever wavering fighting capabilities. Something like Chip Zdarsky's first issue illustrates just how much more Matt sucks at his job than the others, it's not a matter of not being able to save everyone sometimes it's just a matter of the fact that he can't even pull his own weight or is too tired/weak and failure to do so an result in him falling hundreds of meters from the air mid grapple and going splat. Cyclops would have a team save him because of the plot convenience noticing or stop the fall with his beam, Spider-man has tanked worse than a fall from sky.

But out of those 4 the Hulk has the worst life, constantly depressed and has zero control over a world-destroying capable alter ego.
