i loved Penn...it's really a place where i can see myself for the next few years. i'm still deciding too, but so far Penn is looking right for me. great program, great research if you're into that. didactics help on the boards for specializing, but at the same time, i'd say it's teh ivy with the most clinical exposure. dentsim was really sophisticated. love the feel of the undergrad campus. the faculty make you feel wanted at the school. you're not just a number there, but i feel they value everyone in the class. honestly, it's looking to be the best choice (other than the money) right now
