Did you happen to read the Terms of Service when you signed up? You're probably like, "Ah, what's that?" Well, go back and read it if you didn't. This is what is known as a "vs." thread. You're asking people to choose between two parks, both of which are pretty well loved by everyone on here. A lot (two words, not one) of people like those parks and they're very different from each other. You're trying to stir up the waters to get people pitted against each other, and we have better things to talk about, like "Hey where's that Ultra Twister track headed?":)
Here's the point I was trying to make in a more subtle way. If you're going to ask people to compare things, it usually helps if you're starting with two things of relatively the same value. So, I could ask people which would you think is better, an H2 Hummer, or a Jeep Commander?
But, if I asked the same question but phrased it as "Which do you think is better, an H2 Hummer which I think is awesome, or a Toyota RAV4, which some people love too, but gee it's no H2 Hummer? So now we're not even comparing anything remotely the same and I'd be expressing a bias towards one product. I would've rendered the other person's viewpoint null and void, if they did go for the other option.
This is where you come in Jeff. Let's say I answer that I love Knoebels. You then would pounce on me, and say "But, they don't have Phantom's Revenge, Pittfall, Exterminator, a Skycoaster etc., etc.
There are so many major differences between the parks (especially since Kennywood no longer has the ticket option), that you can't really compare them.
