I would probably fly the Prem + over the biz bed for TATL on that bird, i'm used to longish 5-6 hours flights within america on AA F, that would do me just fine since similar seat but leg rest + more leg room. Possibly the only scheduled service i wouldn't be bothered in not being in J, esp if traveling with the other half. The main thing they got right here - copy the AA F arm rest space between seats, it makes a huge difference, and would make me consider flying WTP. As it is, i'll stick with J or just not travel!
