It's tough to compare the two since the Panny has a digital amp, while the Pioneer is more traditional. If I'm not mistaken, I think the Pio has more connectivity options, too.
I'm not familiar with your speakers, though I think either one would do a fine job driving them. Be sure to check the power ratings for the speakers and receiver to ensure that they are a match.
Personally, I would lean towards the Pioneer, though I am a bit biased since I have never owned a receiver from Panasonic. The XR-55 and 1016 are extremely popular, so I think you'll be fine either way.
