New Head Unit

Calling all Audiophiles.
I'm stuck on 3 units. First off I'm a huge Panasonic fan but, in my long line of Car Audio Head units I've had Pioneer, Clarion and Panasonic. So I guess I can't say I'm sole to one but, my last 3 have been Panasonic. Not for wear and tear but, because I've changed vehicles that many times.

The models I'm looking at:
Pioneer DEH-P4800MP

I'd go with the Pioneer. That's my personal take, I just like the look of it the best. And Pioneer has a very good history. I know nothing about Panasonic.
