The only one that really pissed me off was a distro called biglinux. It's arch based and very popular in Brazil. It's actually very stable. Everything works great. It's got some nice features.
Butttt, it uses latte dock or panel (kde). They have built in presets for how to arrange the panels and what not. It's nice, however, I was trying to move some panels around from the base options and broke kde. I wasn't doing anything more than changing GUI settings and the whole desktop broke. I seriously don't understand.
