I can't comment on the specific model Samsung that you are inquiring about, but I think the PQ on my BD-P1600 is just fine. Looks as good as my PS 3 to me, but I haven't done any real critical comparisons.
I will say that Pandora seems like a nice feature and I have a few channels set up on mine, but I never use it. I guess it would be nice during a party or something.
