I don’t have any experience with Tuxedo or Framework, so I can’t really comment on those 😅
I have definitely heard Lenovo ThinkPads are great though, and I’m currently rocking a Lenovo Legion Slim 7 which has been fantastic so far (albeit I JUST got it and I’m rolling Windows on it with WSL2 Debian, so not exactly a pure Linux experience).
I see you mentioned JS, but not TS. If you haven’t tried TypeScript, you 100% should! It helps a lot at scale.
Also, I really do recommend Rust. It’s pretty awesome having the errors actually make sense, and it’s not as complicated as the hype makes it out to be (until you get into async rust lol).
As others have mentioned, C# is also awesome.
