I have a Dell XPS 13 and have run various flavors of Arch without any problems. I didn't try Ubuntu, however.

Sleep and suspend just work. Battery life is good - typically 5-7 hours. Before this I had no problems with a Thinkpad and even on a MacBook Air (2012).

Maybe I'm just so used to Linux now that I don't notice problems since I've been on it since 1998-ish except for a short stint on OS X.

Dell support is terrible so I can't recommend the XPS. When I had a problem with the battery they wouldn't replace it under warranty since I was not in the country where I bought it, which is total BS.
