heh, I'm one that thinks Bryce's GUI is clunky, actually one of the few programs I ever got that I HAD to read some of the manual before I could do anything with it, and the material editor is still almost entirely opaque to me. As for the panning speed, I just tried it out with Vue 5 pro studio (loaded a bunch of terrains and set them up to 2048 resolution). And strangely, only had it slow down with view modes OTHER than smooth shaded LOL (ie wireframe). So I loaded up vue d'esprit 4 and loaded a huge scene I had made with it, and yep, had to go to options to tone down the drawing and redrawing quality to smoothout the panning. I'd say the two things I prefer about Bryce are 1)that "foamy seawater" material, even though the Vue's foamy water material looks more like actual foamy seawater, I like the bubble effect in the Bryce material for OTHER purposes. And I haven't been able to match it in Vue ...yet ;-). and 2) The ability to do LOW ground fog close to the camera.
