Manjaro is....tricky.

I've called it an Arch based distro that kinda sucks at being an Arch based distro before, and I stand by that. You can't treat Manjaro like you would EndeavourOS or Vanilla Arch Linux because of how Manjaro decides to do things: essentially, updates are held back by a couple of weeks for better and worse instead of being released as they're made avaliable. While that means it can catch disastrous things like the GRUB issue another user pointed out (Manjaro was unaffected by it IIRC), it also means the system is prone to breaking itself more often. You can forget about using the AUR if you're using Manjaro–or well, you can, but the AUR and Manjaro are nortorious for not playing nice with one another because of the latter's tendencies to hold back packages.

Personally, I wouldn't recomended. I had more trouble with Pop_Os!, yeah (even tho i can admit that's my favorite spin of Gnome 3), but Manjaro just tested my patience more than anything else. However, If you don’t mind being extra careful with what you install (really that’s standard practice for any distro, but hey, I’ve never found a WIP package that messed up my system anywhere other than when using Manjaro, so make of that what you will), are willing to tolerate constant mild to severe breakage, and just using Flatpaks and appimages over the AUR, then give Manjaro a try.
