I’m with you on the “FOSS office alternatives are shit”, but unfortunately MS office is also shit. Google is the closest I have found to a good office suite but even that is becoming a bit chaotic and awkward. LyX is a promising word processor but also pretty awkward to use in its own way. I’ve got nothing, there.
As far as gaming, this sound less kind than intended but you deserve any shit you get for saying Linux gaming is bad these days. Apart from a few AAA games with anti-cheat where the devs just don’t want to, basically every game just works without any extra effort. Even obscure indie games. I can’t think of the last game I wanted to play that didn’t run on Linux, and often it is better under proton than Windows or native.
If they sound different they’re not lossless. (Or they’re different masters)
