sound and efx wise(except for ac piano)PA sounds much better than g1000 IMHO and I'm sure most will agree.+more synth editing power(in a sub 2000$ arranger KBs)it's sure hard to beat.

g on the other hand it's older tech,better keys, and ofcourse harder to get rid of(with a reasonable price) if you want to upgrade.

by the way PA has 2 seq play(ie you can play SMFs non stop ,even do volume crossfades ,play one SMF stop in the middle,play other etc).
