Montu is definitely my favorite of the American inverts I've ridden. My ranks go:
1. Montu
2. Talon
3. Great Bear
4. Batman the Ride (SFGAdv./SFMM)
5. Silver Bullet
6. Raptor
7. Flight Deck
I've ridden 3 and I would rank them...
1- Hydra
2- Medusa (East) (Before Bizarro)
3- Scream!
Hydra I found the smoothest of the 3 by far and the layout was much more unique then Medusa or Scream. Medusa was great as well, I really didn't enjoy Scream! much.
While at Six Flags Magic Mountain a few weeks ago a woman in line for Riddler's Revenge was telling everyone it was the fastest coaster in the world which I almost hope she was just joking cause if she turned around Superman Escape & Goliath were visible faster coasters.
Another one that didn't occur with me but on AWITP Podcast with Pat McCabe he described how someone said Kingda Ka was not a brand new coaster in 2005 because it was relocated from Hershey Park.
Those are the two I remember off the top of my head.
