If you don't feel that you are getting enough quad development from squats, then traditional deads are a great way to do that. Also, you're going to be able to pull more weight with traditional deads, which will spur more muscular development.
That being said, Romanian deads are the best way to hit the hamstrings in my opinion, and they are a great compliment to squats, which primarily hit the quads. Romanian deads / Squats will make sure the entire leg is being hit in the most efficient way.
