Like you I looked for an alternative to Proton and I’ve been using tuta for a couple of years now as my main mail. You can create aliases with your own custom domain. My only non important complaint is that you can’t use other email clients (Thunderbird, K-9), due to their encryption I guess. They are also fairly active in Mastodon.

Linux gaming is at a point where the only games that don’t work are the ones being actively blocked by the developers, mostly through anti-cheat systems. Just install a stable distro like Ubuntu or Fedora, and use Steam, Lutris and/or Heroic to manage the games and compatibility layers needed for them.
