I've recently chosen plain CSS for a project at work. Haven't got that far yet as it's been mostly backend work so far but for what had been done it's been good. I'm just a bit worried that it's going to look wrong in different browsers but I guess I'll burn that bridge when I get to it. Luckily I don't think there's going to be any safari users.
