The main complaint, I've seen about 2012 Panasonic players in general are: network and streaming complaints. While i didn't try the 220, I did try the 87, and while it was the basic feature set of the 2012 models, and I didn't have any issues with streaming. I found that the interface for networked streaming services ran slower. (Netflix was considerably slower to load then on the sony, and it's the same interface now.) The other complaint i had, was the 2012 Panasonic players don't seem to be fully compatible with my 2009, panasonic plasma. While, the operations of the tv turning on, and switching to the player's input worked, and turning off the tv also turned off the player, i was not able to control navigation options from the tv's remote, even though the tv and player recognized each other.
I'm happy to say the sony works perfectly in this respect on both the panny tv and the sony tv.
I've owned 3 panasonic players through the years i've invested in blu-ray, while they are wonderful players, and i'd certainly recommend them to people, for me personally i've gotten to like the sony interface and set of features as a primary player for each room. Living room, and bedroom.
