I didn't watch them back to back - but just from memory I could tell the HD was alot crisper looking than the BluRay. The BluRay seemed a bit smooth looking to me. It also seemed that the fleshtones on the HD were more accurate. I will watch a few scenes back to back sometime to verify my bias.
Then again... the real difference may be between the HD-AX2 playback quality vs the PS3 I use for BluRays.
