Which Pile of Bunnies is Better?

I spent some time today messing with the Bullet / ODE demos, specifically comparing and contrasting collision detection performance and mesh-mesh interactions between the two. This has left me with two very large piles of Stanford bunnies:

(Bullet Bunnies)

(ODE Bunnies)

I know, I know...you can't really tell which is the better engine by just looking at snapshots, but based on dropping these guys on top of each other (and shooting cubes around, among other things), I think I'll try to plug Bullet in first. Its collision performance looks a bit smoother (which also seems to be the consensus reached in various programming forums that I visited).

...Although, Pixar has been known to use ODE. No, no...Bullet for now. I'll let you know how it goes.
