Interesting poll! These two definitely seem like they are the flagship Six Flags parks of sorts, and both have stellar coaster selections! So, it might be fun if I offered my winners for some of your matchups (but do bear in mind that I have visited neither of these parks):
- Nitro vs Goliath: I'm sure Goliath is a fine ride, but I adore a good B&M hyper, so I'll go for Nitro.
- Kingda Ka vs Superman: I'm going to go for Superman here, as I actually hear quite a lot of people rave about it, whereas the average opinion on Kingda Ka is far less positive.
- El Toro vs Twisted Colossus: This is a tough one. Both look awesome, but I'm going to go for El Toro, as it arguably looks to have some of the best ejector in the world!
- The Joker vs X2: This one is somewhat easier; X2 all the way for me! I'm sure that Joker is fun, but X2 is just on a much larger scale generally; I'd almost argue that Joker vs Green Lantern First Flight would be a fairer comparison. However, I'm not really sure whether 4th dimension coasters would appeal to me as a ride type in general...
- Bizarro vs Scream: Very hard one, as they're exactly the same layout. However, I'll go for Bizarro as it generally seems to get rated higher for some reason.
- Green Lantern vs Riddler's Revenge: I'll go for Riddler's Revenge here, as the layout seems marginally more original and the ride generally seems to get higher ratings.
- Superman vs Tatsu: I'm afraid I've got to go for Tatsu here, as it seems like a far more extensive layout than Superman.
So that's 4 wins for SFMM and 3 for SFGAdv, so
Six Flags Magic Mountain is my overall winner! This matches up with my overall feelings on both!
