You'd be happier with the pioneer, and it's possible to 'fabricate' the aux input for it. Sony headunits (especially the cheaper ones) have gone down quite a bit in quality over the years, and generally don't sound very good.
Panasonics are alright, as long as you don't play CDs in them and expect them to work properly. Pioneers seem to have the least number of problems out of Sony, Panasonic, and JVCs.
You can get the Pioneer DEH-P3700MP for $150 from Crutchfield (probably cheaper elsewhere), and either fabricate the aux input (not hard) or buy it, and be better off than the list you have there.
But, if you're stuck on those, i'd take the Panasonic over the Sonys you have there.
