B&M consistently make better coasters than Intamin with a far superior quality and service.)
Better? Yes. More exciting? No.
I like Swarm, but Stealth is my favourite ride on that park. Now, B&M obviously rule towers, for their two world class classics (as they now are).
That though, is equally down to the brilliance of the design and surroundings. Otherwise, why does everyone take the pee out of inferno? I think it's a far more decent coaster than people give it credit for, as in fact is Swarm, so I am far from anti-B&M. Indeed, I love them all bar air - which I really don't like.
Some of the most daring and insane coasters on this planet are built by Intamin. They do get it wrong. But B&M just do not push the boundaries anymore like they used to. Think of the variation that Intamin use, and are still developing crazy ideas like the pneumatic drop system. B&M would never do something like that.
For bravery, innovation, sheer insanity, I would always go for Intamin. Though you know the likely hood is that in 10 years time they'll be, er... yeah lol, where as over all B&Ms will go on for as long as you maintain them well.
B&Ms are very, very classy, and I like them a lot but I'd definitely rather have some Intamin madness - even if it isn't a woody!
