Well, to be fair, Fahrenheit is one of the coasters I really want to ride right now. It's actually probbaly my most wanted, alongside T-Express and a few others.
However, I'm not a fan of inversion after inversion, which is what Fahrenheit is. Yes, inversions can be good, but Fahrenheit doesn't have the mix of a launch, few inversions, twists and turns, other elements, and airtime hills thrown in there in an even mix like Maverick has. It seems to mostly focus on inversions like I said, whereas Maverick covers all across the board.
I think Maverick is a great coaster, but seeing as I haven't been on both, I won't vote. I think it does look better than Fahrenheit, but only by a little bit.
