I want some opinions about which version of Linux should I get for free, I'm want to start using and learning that program, I want something popular most used and the most features possible. Thanks a lot for the Info

The right hand side of this (http://distrowatch.com/) page will give you an idea of which distros are most popular and here (http://beta.linuxiso.org/) is where to download them or a quicker way is to check out some of the Linux mags which often have distros free on the mags cd.
I have used Redhat, Mandrake and Suse and they are all good to start with.
