1. The language of the forums is English. Your question was which version of Linux would we recommend.
2. The best answer is
a. go to a site like this:
http://distrowatch.com/
b. Try several live CD's of different distros. (Almost every one of them allows you to choose your language, Spanish in your case)
c. When you find one that you like then you can install it permanently.
3. Remember everyone is different so do not depend on specific recommendations. Try them for yourself. I use Debian and it's good for me but your taste may be different from mine.
