I occasionally have to use a 'regular' Sony BD player over at the in-laws and it is painfully slow to load and play compared to the PS3.
My last post was kind of tongue in cheek. I was thinking of the VCR and CD player. Eventually there will be no difference between players, but we are not quite there yet.
The scaling of DVDs the PS3 seems pretty good. I don't know if the Oppo is better or not. The Oppo being a universal player makes it a better choice in my mind, but at the time I was looking at the PS3 for some games for my son so it won out.
