I'm looking at two HU the Panasonic CQ-C5401 or Kenwood KDC-MP6029.
Theres a price difference of $80 more for the kenwood. but i'm not worried about that i want what will give me better quality, control, and options for upgrading other components.

i know theres websites i can find this information but the information doesn't mean much to me.
Thanks for any tips on what's better.
