It's been a while since I've been on here!
Anyways, I rode Orion WAAAY back on July 8th, so it was still fairly new. I got 2 rides on it, one in row 7 and one in row 4, and I forget which one I preferred more. Besides that, I thought the ride was incredible! It's my 2nd favorite B&M behind Fury 325, and my #9 overall. I thought the "wave turn" was fantastic and gave such a great sensation of airtime, I thought the speed hill was FULL of sustained ejector, and I thought that, despite being trimmed, the floater hill was better than any hill on Intimidator at Carowinds. Orion also gave me a feeling that I've never experienced on any coaster ever, something about it really clicked with me and I don't know how to describe it. However, if there was one part that I was let down by, it was the helix; I didn't get any resemblance of a helix that would/could make me grey out. Other than that, it's a fantastic ride!!
In terms of how I'd rank it among the other gigas? Well, I've been able to ride all 5 North American gigas, and I find it so hard to say "oh it's my 3rd favorite of the gigas" because (for me) there's a HUGE gap in my preference of Leviathan and Orion. For me, Orion, Millennium Force, and Fury 325 are all inside of my top 10, yet Leviathan and I305 are considerably far away from it (I305 more-so than Levi). So I largely prefer it to Leviathan and I305, but I slightly prefer Millennium Force and Fury 325.
