I have a high-end Pioneer in my car and I like it. But, several years ago, I replaced the factory receiver in my truck with an inexpensive Panasonic. The Panasonic blows the Pioneer away in all aspects.
I have since purchased another Panasonic because I wanted XM capability, and I am very impressed. The Panny has a very clean sounding high power amp, with lots of connections and adjustments to tailor the sound to your vehicle.
The Pioneer is a pain to set up, with their menu system. Once set up, it is easy to use. But, every time I disconnect the battery for maintenance, I have to go through the arduous task of setup again.
The Panasonic is a breeze to setup and adjust. A very intuitive menu system.

I purchased mine on Ebay for a substantial discount, but Crutchfield is a quality supplier.
I highly recommend Panasonic!
