All of which is amazingly wonderful, valuable, truly treasured knowledge for the ages, but.
If you were to line up ten park-goers and ask them to explain what "old school B&M" means, the overwhelming majority would either stare at you blankly or start making reference to various gastrointestinal functions. All ten may do so. If you're lucky, one might begin asking you how much you know about Bollinger & Mabillard, start reciting financial and managerial details, rattle off their currently deployed ride portfolio, and then ask you when you started looking at B&M rides and why you're not wearing a B&M t-shirt while you're talking about B&M coasters. Well, then. Not everyone can be a true fan...
Point is, "world class" isn't an objective measure. The majority of riders aren't going to look to a ride's parentage to decide what's "world class," which is a material point, because the majority of riders comprise the base for said world.
Theming for these kinds of coasters, no matter how great it may be in a given case, is frequently a sideline, because they're designed to be dismantled and sold to other parks as seen fit, and there's no guarantee that the new site will want a coaster themed to Hulk, Camelot, or whatever else is in place. Blending in is more a function of what Universal put together around it than it is choices for the ride construction itself. (The whole "launch simulates Hulking out" idea falls a little flat when even Slinky Dog launches nowadays.) What sets aside a coaster as "world class" today frequently doesn't hold up once other parks catch up, and they most certainly will.
