As someone who understands windows fairly well, but until recently couldn't use the command line to save my life, I started dual booting Ubuntu and it's pretty easy to figure out once you understand what you're looking for. Only things I'm still trying to get running are alternatives for the stream deck software, iCUE, and voicemeeter, but I havem't really invested much time into them yet.
Sometimes people get caught up trying to find exact matches for software, when instead it's a combination of tools that gets the job done on another OS. The annoying thing is learning new toolsets -- but it's only annoying until you know them.
Yeah I don't expect to get all the functionality in one piece of software, so I'll have to cobble it together. Of course, icue depends on the .net framework so it's not getting ported, and the other 2 just don't have an official native linux app. Jack mixer is my current target for voicemeeter, but I have to start researching the others at some point.
