It also upgrades in place nicely. Excellent distro for Ubuntu and Mint to base themselves in.
I personally prefer using EFISTUB instead of a bootloader, and this was very difficult to do on Ubuntu last time I tried.
Mint might be an OK stopgap, but I wouldn't call it a long-term solution to Ubuntu's snap infestation. Just like you won't get a good OS by playing whack-a-mole with the various workarounds you have to do to avoid Windows' latest user-hostile bullshit.
I learned a lot about linux when I decided to try Arch. And as OP, I also never looked back :)
The Arch Linux Wiki is a fantastic resource.
Heck, even just reading the installation guide gives you a better understanding of how a Linux machine operates.
