Eh, it worked well for me, but I’m easy to impress. I switched to Linux before Steam on Linux was a thing, and I made a Steam account when it came to Linux back in 2013. It was a bit unstable the first couple years, but by 2016 it was quite stable. I think my first Steam purchase was in 2015 (Rocket League I think? I don’t recall), and almost everything before that was Humble Bundle keys.
When Proton was released in 2018-ish, I suddenly had a ton more options, and I started to purchase way more games.
Things are way better now, but I was ecstatic to finally have a gaming platform care about my OS.
