This is insanity to even compare the two. It's obvious that neither offers more than the other. They are both equally qualified to kick your*****when it comes down to it, and it is plain foolish to assume otherwise. I imagine that everyone that pre-qualifies a coaster because it looks cooler, or taller, or has a steeper drop, is probably a bit too attached to their "home" park.
If people actually rode the coaster, they are allowed their comments, because they have bearing. That still doesn't make any difference, because the ride is still subjective. Perhaps I will ride the SD2K on a rainy day (it does rain a lot in Japan). It might very well suck. Who knows? Who cares? I get to ride it, and actually compare it...how many get to even do that. Opinions are great, but they are just that. I will let you know how the ride is from my perspective. I will take pics from the top, and scan them into a website for a friend of mine. Then you will get a first hand view!
