Start with Gentoo or Arch
I wouldn’t recommend arch to general users. I consider myself a general linux user, and figuring out Arch, even after the installation hurdle, wasn’t easy for me.
is like fixing windows when it doesn’t
I don’t think Arch really makes that easy. Although, I guess archwiki is pretty great. Even arch forum helped me a lot with respect to other disto.
There is Komikku for linux though it’s kinda limited to sources it supports. Komga is a nice self hosted option with support for Mihon and all the tachiyomi forks for android. There is a tachiyomi fork called Komikku (different from the linux app) that I like.
