I commute from DFW to PHL E190 and it really isn't bad at all once you're a lineholder. There are 8-9 mainline flights a day (more than half Airbuses with 2 jump seats), and just about all of the E190 trips are commutable on at least one end. Once you have a line, you can reserve the jumpseat and not worry much about the commute unless there are thunderstorms, etc.
I absolutely hated commuting to reserve and wasting away in a crashpad, but fortunately reserve was only about 2 months short call and 2 months long call for me. I was able to have weekends off and all commutable trips at the one year mark and now I'm being withheld from the Airbus while bidding in the top 10% on the 190 . Not a bad way to wait it out until I can hold DFW.
Unless I lived in a junior AA base or on the west coast, I would definitely pick the 190 again. The advancement is very quick and you can bid off of it in time to get second year group 2 pay. The only real downsides are having to go through another initial and not being able to pick up trips out of other bases.
