If you are looking for a more traditional response then AA/US has more of the country covered with more conveniently routed flights than DL.
For me United is still my best option.
I would never wish Spirit on my worst enemy.
sadly if you dont fly WN, then from IAH, you are hub-trapped to UA. Although AA does offer a LOT of daily flights to DFW so you do have a lot of one-stop options with AA.
