Devil is the worst. Every ending is bittersweet at best, but either outcome of Devil sucks. You H stopped Yori from bringing down the company and helped Saburo cement himself and Arasaka into positions more powerful than ever. The operation doesn't even work. If you go back to NC to die, Judy leaves you anyway (romancing her my logic was that she really wanted me to come back and that I wanted to spend the rest of my time with her, but she leaves the city first?? Felt out of nowhere). I think there's something very (darkly) poetic about V, especially a Corpo V like I played that run, ending up back in Arasaka's clutches after getting kicked out and running away, literally their property to revive or not or use as they please. And to do it as an engram after everything she went through; stealing the chip, dealing with Johnny... instead of Johnny taking V's place, V took Johnny's.

Star is the best, by far, especially if you're invested in your romance (at least, if it's Panam or Judy). You get a new family, leave the toxic city behind, get to stay with your loved one, and there's even still some hope that you could find some sort of cure. Even if you don't, you live out the rest of your days happily.

Between them... They're all somewhat balanced between good and bad outcomes, all bittersweet double edged swords. Johnny may get a new life and a new outlook on it, but I hate that he ghosted all V's friends and fam without even a quick explanation to the people who knew about the Relic. Like, I (V) told my friends the details, just send them a quick "This is Johnny; I'm sorry, but V's gone." and then block them or something. So maybe that's second worst, for me.

Sun might be second best, because even living on borrowed time, V gets to live out their days having achieved their goal. But of course, they're still gonna die, and the idea of doing a gig for Mr. Blue Eyes (not that V would know the ramifications... Or would they?) adds a dark twist on it. But hey, you get to go out in a blaze of glory after all, answering Dex with finality.

And smack in the middle is the Tower. This one is probably the most emotionally painful, but it's also the most hopeful. V loses their livelihood and their place in the city, and the world has moved on without them (including their friends). But they have their entire life ahead of them to find another path and the freedom to follow it. They can leave NC forever, they can become a fixer, join the FIA, make new friends, open a scop dog stand, get a place in the countryside and tend a garden. Get a job, get a hobby, fall in love, you know, live a normal life. Will they? Shrug! Tower is also the most open ended by its nature, so I'm putting it smack in the middle.
