And why do you use them?
Although I don’t use them, the Jetbrains products should be near the top of the list.
Reaper. Great usability and decent Linux support out of the box (looking at you, davinci resolve). Generous free trial and a cheap one-time payment for a license. LMMS has served me well and is fine for basic stuff, but reaper is a whole other level, both in features and usability. I’ve heard good things about ardour too but have yet to give it a try.
Steam probably.
Yup, as time went on, I simply felt less need to have proprietary software on my system. Steam remains as an exception; simply by virtue of having no F(L)OSS alternative (AFAIK).
Valve has put a lot of work into helping WINE & Linux. Even if it was a selfish play to break free from Microsoft & other app stores to lock those into their marketplace fee, I can’t help but be grateful for the better ecosystem & uptick in users. Since they are privately held too, they aren’t in the same business of chasing quartely profits or making the experience worse & worse by selling your data & slapping ads everywhere.
DaVinci Resolve is THE video editor on Linux. Unfortunately the libre apps for it don’t get even close, to the point that even with all the limitations in the free and paid versions, it still is the best option.
Also shout out to Bitwig Studio, although I don’t use it.
I like Sublime Text and Sublime Merge and use both daily.
