My experience with Mint the last 8 weeks has been... mixed.
My biggesst issues:
-It handles two monitors with different resolutions poorly. I settled on accepting that one screen has just bigger UI now. There is an experimental setting that allows individual scaling per screen, but some apps don't seem to use the systemwide scaling. It basically creates more problems than it solves.
-Dark mode is random. Some apps don't support dark mode, but Mint still forces light fonts. Which makes those fonts unreadable on the light backgrounds.
-Window management is... weird with two monitors. If you have your screens setup in a certain way, windows will appear partly off screen,aking them undraggable or closable. Some windows you can just WIN+arrow but some popups don't allow that.
Permissions can be a pain in the buttocks. Some flatpaks don't give the right permissions, so you'll be googling and sudo'ing your ass off at times. How can a flatpak for Arduino NOT give permissions to use USB? Dafuq?
Also, any permissions outside your home folders can (out of the box) only be changed through commandline. Which makes it a pain to install, for example, fonts, unless you dig through the 6 font managers that software manager shows. 2 of those font managers don't have a gui, 1 can only install 1 font at a time, so after trying 3 programs you finally find one that works.
-Now that we talk about the software manager... It can be a pain to find the right stuff. Sometimes you search a program, and you'll find 7 versions because thank FOSS and all it's forks.
-Most documentation and questions are answered with using commandline. And sometimes, as a noob like me, you'll damage more with those answers than you'll solve.
I have had multiple OS wide hard freezes when unplugging USBs from an external USB hub. Only hard resetting the PC worked.
What I like so far:
-You can split the explorer in to two navigations. Super useful.
-you can fully customize your start menu and launch bar.
-the backup function is amazing
-most steam games work great
-it starts up rather quick
-it doesn't track me like Windows does.
Might try Pop OS soon, although I also accept that switching an OS can just take time to get used to. Took me a few months to get accustomed to OSX years ago when I had a Mac Mini for 6 years.
