I like AA transcons in First on any aircraft since they have in-seat power for my laptop. Alaska doesn't. Their digiplayers are a nice bone to throw the F passengers, though.
Otherwise, their food and onboard services are very similar. So if it's just TV you want, bring a laptop with an airplane power adaptor....
Why not clue us into the route you're taking?
Forget just F, AA has powerports THROUGHOUT almost all of their aircraft. It is a huge incentive for me to fly AA, because I know that I will always get to plug in my laptop.
To the OP - I would suggest splurging on $100-200 on a portable DVD player. Your selection of movies will be FAR better than any airplane in-flight entertainment system, and you will be able to take the system with you on any flight in the future...
