"But which Linux?"
Mint. As long as you're asking, you might as well go with Linux Mint. It's a good, solid, stable distro, easy for beginners, smooth, polished. The Mint user community is more friendly than many other Linux communities, and most of the info you get online searching for how-tos are either for Mint or Ubuntu, and as a direct descendant of Ubuntu, most of what you read about that relates directly to Mint as well.
As you learn more about Linux, you will begin to get an idea of what is lacking, if anything, in your opinion, and what else to try if you don't like Mint.
I like the Cinnamon variant of Mint myself. It's not hard to try other desktop environments... experiment, see what feels right to you.
