Personally, ratscloset has always been very helpful when things went sideways for me at CP.  The lightbox (I assume that's what it's called because any time you mouse over it, it says "Lightbox Disabled") is sometimes incredibly slow when moving through multiple images.  This seems quicker since the recent changes.

I also find that CP seems to accept pretty sketchy info from vendors - if I can't figure out what's on offer, I just move along.  I think their search is one of the best, although I also like the rendo results from multiple areas approach.  I used to spend much more there (time and $) but I tend to keep coming back to rendo.

Oh and one other thing, I think it was great that CP and rendo were able to play nice and get the list of rendo items purchased at CP updated on the rendo site.  I'm afraid that just reinforced rendo as a favorite, since so many of my CP purchases were really rendo product.  I think they (rendo) came out ahead on that decision.

I use Carrara, so the poser-centric universe there is not always useful to me.  Given the differences in lights, the landscapes, and phenominally faster render times, I could never go back.  I still look now and then though.  I even picked up Poser 7 Pro on sale a while back - still haven't installed it.  I never use the forums there - these seem more responsive.
