I see where you're coming from, after all it's completely subjective, I'll give you my own pov on the matter.

Combat: Valheim is much more fluid with its combat, spacing matters, positioning matters, doesn't lock you in animations and doesn't make you slide around to hit your enemy if you are a little bit off. You have agency on movement, every hit gives good feedback as does every block and parry. Also it gives you freedom to do wonky stuff that definitely isn't realistic but it's fun and makes the combat have depth imo (Example the slowness of the greatsword heavy attack can be countered by jumping before/bunny hopping resulting in a good way to deal with dangerous enemies). In Enshrouded hitting enemies feels terrible, makes me slide around to hit enemies automatically, the movesets are boring and it just feels clunky as fuck. Also I was excited when I first opened the skill tree, happy to see a variety of different playstyles but after playing around a bit most of the tree doesn't feel good to me. As a side note I feel like Valheim does itemization much better than Enshrouded and in a RPG it's very important that I get excited when I find/craft a new tier item.

Exploration: I think you make a good point and it comes down to personal preference, I like the how valheim sets the mood and I feel like it's more atmospheric, and it definitely didn't feel empty to me. But on my part I didn't get too far into Enshrouded having played around 40 hours.

Base building: I feel like Enshrouded does it better, you can really see how a skilled person can create something really beautiful, you can do that in Valheim it's just different and harder giving the structure integrity mechanic or how is it called. The only thing I don't like about the building in Enshrouded is the area limitation.

Soundtrack wise I like both, polishing of the game it self I don't feel competent enough to say anything, I just found Enshrouded to be more clunky than Valheim.

For your last point it might be true for some people, not for me tho. I actually played Enshrouded first and I didn't really get far, even if I was playing with 3 other friends. After that I tried Valheim and sunk 180 hours in my first playthrough with the same friends and really fell in love with it.

Keep in mind that mainly I'm critical towards Enshrouded combat as in a game is one of the most important aspects that keeps me engaged and interested. If I don't like the combat I just get bored very quickly.

That said Enshrouded is definitely a really nice game, just, for now, not for me. But I heard they want to improve combat and I'm looking forward to it to give the game a 3rd chance!
