If you’re going to use it for music (CD, Streaming) and/or have an older receiver that does not have the latest processing formats, but has a 7 channel input, then go for the Panasonic as it blows the Sony out of the water. (Leave the Panasonic audio processing modes off)
If it’s just Blu-Ray/DVD films your after then save some dosh and go for the Sony.
NOTE: I have compared them side by side, and for me personally I will be getting the Panasonic in the New Year.
Hope this helps
