well, i played both and i can safely say that they are both good and bad. it all depends the way you play them and who you play them with.
and they are very very different. vampire is more serious, dark and roleplay oriented whilst d&d is more... munchkin like (lets get on that dungeon and whack some orcs! type). both have its advantages and disadvantages. d&d would be good to have a different aproach to rpgs if youve only played vampire so far. so buy those books (if you can afford them) and give them a try.
