Yeah I've been on Superman SFA around 100 times (same layout as the one at SFDL, just mirrored,) and I really like it, but it doesn't come close to the one at SFNE. SFNE's has MUCH higher negative g's, more spots with the high negative g's, no flat sections, two amazing tunnels, a better first drop, better setting, higher positive g's, some of the best and most forceful helices around (especially great laterals on the second helix,) and better bunny hops (no trims on them.) SFNE's is actually a lot smoother than SFA's. The only thing that Superman SFA has that Superman SFNE doesn't have is that awesome ground hugging turn where you can actually (and easily) touch the grass at 75 mph.
