If any go with the Urethane one. Fiberglass is very prone , especially in the front of the car, to breaking if you hit a bump too hard and you bottom out. It will crack very badly and it would be big pain to fix. Most people just buy a whole damn new front again rather than fixing. Urethane is much more durable and it takes an imense impact for it to crack. If anything choose the 2nd for durability because there is not much difference in the look of either.
