I'm a Linux newbie,and have been doing a little research into what would be best for me.I've come to the conclusion that I should probably start with either Mandrake or Redhat,but don't know which one.What are the primary differences in the two?Which is easier to use?Which is better security-wise?What do you all use,and why?I found a similar thread to this,but a lot of responses left out why they use the version of Linux they use,and that's what I really need to know.
