I'm quite experienced in Linux but I wouldn't use either. Arch is great if you like to tinker, Ubuntu sucks for the not so libre approach , corporate ties, telemetry etc. I distrohopped before but today I just install my debian based distro and shit works.. Ubuntu I've installed twice before when I was new to Linux, and have had a major issues every time due to official updates that broke internet drivers and other things, that's a fun one when you only have one PC . Not to mention its so bloated that shitty computers that I like to thinker with it have a hard time catching up. The arch thing is also mostly a kind of meme, targeting the more unbearable nerds. People I hated when I was a noob (they will let you know you are) But they are found everywhere and in general I don't think there's more of those people in arch community than anywhere else. It's more of a stab at elitism than arch specifically.

I see a point in arch but zero in ubuntu.
