After flying an AA 738, I can testify the seats on AA are definately softer, more supportive and more comfortable than CO. There is also abit more legroom on AA.
I have not flown any other aircraft type AA operates, so I can't comment on the rest of their fleet. Right now, the two most comfortable domestic coach seats belong to jetBlue and Delta (refurbished cabins only).
