Not heard of OSPRay, interesting. I personally think Mitsuba is the dark horse of free renderers. Blazing fast, good highly modular design, good docs, super easy Python bindings, GPU preview. The only problem is it's a one-man show, and the one man seems to have been doing other things lately. Nevertheless it's the renderer I think deserves to become the "standard".
