I prefer Mint just for ease-of-use, really. I'm not a new user, by any means, and over the years I've bounced between Red Hat, openSUSE, Ubuntu, and a small handful of others that escape me at the moment. But I'm also not a power user.

With Mint, I don't have to tweak things, really. I can install and just go about doing what I want to do. As a bonus, guests aren't left scratching their heads as much if they sit down at my computer to browse the web or pull up a video. It's Windows-ish enough where they can muddle their way through with minimal issue.
