I agree with these people, if money isn't a problem the turbo distortion is a bit better, but you need to think of how you want to sound, the tube screamer sounds good for somethings as well. If money is no problem at all then get like 10 pedals and you can have all the distortion variety that you'll ever need. it really depends on your style and what you want to sound like (Deathmetal sound w/ folk song!?!?!)
