I actually went on both on a road trip a few years ago. We did SFGrAdv, Dorney, Hershey Park, BGW, and Kings Dominion. My wife's and i's favorite of the trip was Apollo by a landslide. Highly recommend a night ride on it for your first time. We also enjoyed Nitro but thought the drops, terrain, and overall layout of Apollo was just far superior. I would also rank Goliath at SFOG ahead of Nitro as well.
