So for all people that are on the fence about switching to Linux: Here's a sort of review and starter guide from a guy who switched to Mint about 4 weeks ago.
Are you someone who mostly plays non-competetive games (games without anticheat) and browse the web? You'll probably have a hassle free life on Linux. Steam's Proton layer does a lot of heavily lifting. Even if games are not officially supported. Turn the compatability on in the steam settings.
If you play VR or competetive games, it's a different story.
VR is dependant on the headset. I unfortunately have all Oculus Headsets, which there is no good controller support for right now from the open source community.
Anticheat simply doesnt work on Linux.
Design software
From what I've read, the affinity suite now can be used through Wine (a program that lets you use windows apps on Linux)
However, from my time with Wine, it is hit and miss. One update from either the application or Wine can break everything. So it is not reliable, unless you freeze all updates from both the application and Wine. Wine can be great (working out of the box) but also the biggest pain in the ass with hours of debugging. Stay away if you dislike troubleshooting.
Inkscape can be an alternative to Illustrator if you don't do heavy design work.
I haven't touched Gimp for about 6 years (used to be my main editor) but when I switched to photoshop it qas no competition. Don't know what the state of Gimp is now, will try it over the coming year.
music software
Cubase or any of steinbergs plugins outright will not work on Linux (unfortunately my main DAW)
However, I will probably switch to Bitwig (native Linux), which looks really promising. I got some VSTs working through Wine (all arturia stuff works great) but have had hours of troubleshooting without luck with others.
Use Yabridge as a vstlink for windows VSTs.
If you're a professional musician with thousands of dollars in plugins, I'd be hestitant to switch to Linux. You'll be dependant on Wine a lot, which is kind of a pain to rely on for professional use.
overall tips
Might be a bit controversial, but if you're a novice: don't dump all the solutions you find online in your terminal. Actually, try to use the machine as much as possible like you normally would on Windows, unless you want to do Terminal stuff. If you dislike terminals, you'll only be frustrated by all the terminal advice people give you, which might even break stuff on your machine.
Try to download .deb packages from the official sources.++ Software center on Mint is great, but will moatly be outdated or flatpacks. Flatpacks can work, but I've had many issues with permissions and flatpacks (like an arduino flatpack that didn't give permission to use the USB port....)
Welp, I'm out of time, so I'll just randomly stop my reviewish/comment here
