Personally I'm not looking an OS that is "not so bad", the initial impression should be "this is great" :)
Ubuntu is kind of the “Windows” of the Linux world
That's also the thing, I switched to Linux because I hated using Windows, and I don't like how Microsoft operates. The last think I want is a distribution which tries to be Windows made by a company which tries to be Microsoft. It's of course an exaggeration, and Ubuntu doesn't do EEE and patent trolling as far as I know, but at least for me it feels like they're going in the wrong direction when they keep reinventing the wheel, forcing solutions that users don't want, and generally trying to create a "one size fits all" desktop. I'm not against it, Ubuntu is probably a good choice for some users, it just doesn't fit me. I used Xubuntu for many years, and I also tried both Gnome and Unity at different points, but currently I use Fedora KDE.
