I've known a bunch of people who like Bridge over LR, but to me, I think the tools especially the non destructive edits make LR a better product.
Before LR and Aperture I think we only had pure DAM products like iView Media Pro which is now Phase One's Media Pro. Bridge made sense then since you could use that in conjunction with PS. Now with the sophisticated tools and DAM features in LR, it doesn't make too much sense - at least to me
