I can attempt to shed some light on the GCI discussion. I have only ridden two, but I tend to think I got the best and the worst of GCI, which really is not that bad. Prowler being the best, and Terminator being the worst. Terminator truly has nothing compared to Prowler. I got off Terminator more disappointed than any other coaster I have ever ridden, because all I had heard was how awesome it was, and I was expecting Prowler epicness. Didn't happen.
My 100 was Voyage. I had planned it out perfect for that.
#94 was Prowler. I then rode, Mamba, boomerang, Timberwolf, and Patriot, with Terminator: Salvations in between. Had to fight not to do the Wacky Worm credit for 100, it was tough.
Funny how #100 is tied for number one, with Prowler.
