I hope you'all forgive me up front, cause by the time I've finished, you'll probably all be sick of hearing the KING of all Inverts!
B&M alone have made some 27 Inverts world-wide in the last 14 years or so, and they are far and away considered the best and the leader of "pure", traditional lift hill Invert coasters--or any coaster that they make for that matter.
In the 5 years before, and more surprisingly in the 9 years since; No Invert has come close to Alpies combination of size, speed, terrain layout, inversion elements, and thrill intensity.
Some coaster buffs might try to tell you that Wicked Twister @ CP is a taller Invert, BUT WT is an Invert only by design (seating), its actually called a "twisted impluse coaster" or an "LIM launch track coaster"--and thats just not the same type of animal. Personally I luv Volcano, The Blast Coaster @ PKD (or CFKD, or whatever Paramounts parks will soon be called

), but Volcano is a launch Invert, so I don't put them in the same group as a lift hill Invert.
Regardless, when you compare all the stats, and have ridden as large a number of Inverts as I have over the years, Alpengeist stands head & shoulders over all. The only Invert that comes close that I've done is its older little sibling Montu @ BGA. Montu beats Alpie and ALL other Inverts in one way, and thats in the # and flow of its inversions--it has 7, no other has 7 or more to the best of my knowlege, and the flow from one to another is incredible!! Now, Montu is my 2nd favorite Invert of all, but just compare it to Alpie in other ways to see where it falls short: lets see, Alpengeist is 195' tall with a 170' drop @ 55 degrees, reaches 68 mph, has 6 large, intense inversions and is the terrain champ; Montu is 150' high (believe it or not, that ranks it #2, 1' ahead of Patriots 149' in 3rd place) with a 128' drop @ 50 degrees--all MUCH smaller numbers than big brother Alpie, and it shows in the riding of each.
I'm going to rank my top 5 Inverts, with stats, you compare your favorite to Alpie, and see how it matchs up;
1) Alpengeist--195'h--170'd--55deg--68mph--6inv
2) Montu------150'h--128'd--50deg--60mph--7inv
3) Raptor-----137'h--119'd--??deg--57mph--6inv
4) Talon------135'h--120'd--??deg--58mph--4inv
5) Fire (DD)--127'h--115'd--??deg--60mph--5inv
Thats my top 5, with Patriot & Silver Bullet as honorable mentions; NO, I haven't ridden all of them, but almost

--my biggest question is WHY is Alpengeist still so much bigger than all rest after all these years?! Did B&M feel that the limit was reached when Alpengeist was made, certainly other parks have wanted as large or larger Inverts, they've had the room, etc., but it hasn't been done, not even close.
I've always been one to say that bigger and faster is not always the most important factors in determining a great coaster ride, but in this case of traditional, lift hill Inverts; Alpie is indeed SO much bigger, faster, steeper, intense elemented, terrain & themed enhanced over all the others, just how could anyone NOT vote Alpengeist the best Invert--maybe just to be different, or to support their home coaster, or to spite the BGE fans I guess. Well, thanks for letting me ramble on about the best Invert in the world--if I can't do it here, where else could I, eh?
