Urethane is better, have to buy special additive to make paint flex but it will last longer that FG. Both look the same after painting, You will most likely have to do some modifying to FG to make it fit properly. I have a Urethane front lip and FG sides and back. Don't reccomentd FG in the front, especially if your car is lowered. Here are some pics of my car.

I have fiberglass/carbon front lip and you can't really tell the difference between the lip and bumper where its painted. If you get FG just make sure you don't hit any curbs when parking and if you gotta scrape then scrape slow.
