Mandrake VS. RedHat [Linux] - Differences?

Hey guys,
I think it’s time to reformat my drives, and I just got a 5gb HD laying around, and I decided to get back into unix based OS’s. I was taking a look at Mandrake, and I was wondering which I should consider. Supposibly, Mandrake has great GUI, but so does RH… Which would you consider for the Beginner/Moderate Linux user?
