B&M all the way! Sure, Intamins are on the aggressive side, but the Intamin reliability and safety track record sure does not impress me. Also, the fact that new Intamin steel coasters now have OTSR's, inversions or not, it really doesn't look that good. B&M coasters on the other hand are glass smooth, perfectly engineered, sexy looking, and something I can ride all day long
So yeah, that's my $0.02.
