Which distro should I use?
Them's fightin words round here. Fuck [Distro 1] and its fanboys. [Distro 2] is clearly superior.
For real though:
Things for you to decide:
Which desktop environment do you want (KDE, Gnome, Cinnamon, cosmic, etc)
Do you want it to be super up to date all the time (quick updates, but may break something)? Or are you OK with slower updates for a more stable system?
Difficulty: How hard do you want things to be? Do you want things to be set up out-of-the-box and lots of solutions online? Or are you willing to dive deep, do stuff yourself and figure stuff out from wikis?
I wanted KDE (objectively the best desktop environment obviously) and started with OpenSUSE Tumbleweed and loved it. Highly recommended. I didn't know about TuxedoOS at the time and that seems like a good place to start too. Now I know more and am on CachyOS and am super happy with it.
