Height does matter to me, but the tallest is not always the best. There are three B&M hypers I like best of all, but there are rides out there that are bigger. Kingda Ka is a little taller than Top Thrill Dragster, but I prefer the lap bar restraint over the OTSR. When it comes to the gigas that I have ridden, I like the taller and longer more (Millennium Force, Leviathan, then Intimidator 305). The tallest invert that I have ridden happens to be my favorite (Alpengeist), but it is not the longest. My favorite three woodens are Thunderhead, Lightning Racers, and Prowler. None of them are the tallest or longest. There are many good rides like Talon, Verbolten, Fahrenheit, X-Coaster, Sky Rocket, Avatar Airbender, and Fiesta Texas' Pandemonium that are not big. It all depends on what the ride is, not always the size.
