RTO gives better quality in almost all cases and is also *faster* in almost all cases (for equivalent quality). That's why we have it enabled by default. The only real benefit to non-RTO object rendering is that you can get "real" displacement on imported objects, whereas those same objects just get bump mapping (shading changes that simulate the same 3D effect of displacement on camera-facing surfaces, including shadows, but have no actual dimension) with RTO. Even with RTO disabled displacement is not always rendered that well on imported objects due to the underlying geometry of the object.
