Good shit. Hopefully you backed up anything important before the switch. Generally good to have backups anyway and use the 321 rule to never lose anything. That's three copies, two different media (hdd & DVD / cloud), and one copy off sight. Although that may be a little excessive for everyone but it will ensure you never lose anything important.

I usually suggest people shop around / distro hop a little. Get a USB, install ventoy, download a few iso's and try a few different distros on their live boot. There are a lot of different paradigms for a distro, different user interfaces, different kernel compilations, proprietary driver options, audio driver options, package management options and so on.

That said for someone new it is literally just easier to use a more widely used or common distro, usually there's better wikis and active forums and it's more likely someone has already had whatever issue you're having when trying to fix something. I usually suggest Fedora or Linux mint (lmde). Although with flatpaks and immutable OS's things are getting easier, more copy paste if you will.
