Switching to Linux

So I am going to switch to linux since my friend said it is better than OS X, but it seems like there are a bunch of versions of it. Which one should I use?

No picture related because I can't find the button to pick one.

not the same anon but he probably means countless embedded systems which use uclibc instead of glibc and busybox instead of coreutils, as well as android devices which use bionic and toybox.
