Mint Cinnamon isn't too bad if you're making a jump from Windows because the User Interfaces are so similar. It's what we have on our school's computers when we're not using Windows in CS class.Mint (mainly with the XFCE interface) as it's simple, robust, and lightweight. If you just want a well rounded user-friendly experience, it works well.
Personally, I use Ubuntu 14.10, although I'm looking forward to the next LTS update in April. I'll probably update.
