Ubuntu. Pretty sure you already have an idea why. Lol.
OpenSUSE. I’ve always had issues trying to use it, from zypper to updates to bootloops. It’s also sluggish compared to other distros (yes, same DEs usually) on my laptop. I’ve tried at least 3x trying to get why a lot of people love it. It’s just not for me.
I’ve never tried Manjaro yet, but coming from Arch and EOS I don’t think I ever will.
The app has always been trash. Idk how people can take using it for long periods of time. When I went back for a bit (during r/place), the deterioration of content was obvious. Don’t take my word for it - even redditors know it’s getting worse. All they have now is the amount of users.
