A sad thing about SFGAm is that they have most if not all of the best genres of coasters, but like you said they are near or at the bottom of the totem pole when comparing them to others of that genre.
RMC, yeah
B&M Hyper, yeah
B&M Invert, yeah
Wing, yeah
Intamin Launch, yeah
B&M flyer, yeah but it is always better than vekoma!
Sad, but also happy because those are all great rides that the park has, just not as great as others. I will make a trip there later this month and ride my first RMC Goliath. Can't really judge for certain this way but Medusa looks the best to me.
