I'd say check the showreel for Vue6 Infinite and see for yourself ;-) Aint no way one can do all of THAT in bryce! Ok, much of it can be, but those atmospheres, the ecosystems, the photoshop style material layering, full displacement support... u aint got those in bryce.
However, bryce IS much cheaper.
