Out of those, if you want to win rather than have fun then go for Kanan/Biggs... The real aces look much more fun though.

So far it has been the most fun. That and tractor pull, however that list ended being a lot to keep track of

I like your Inquisitor/SF/Striker list. I've had success with a similar one except with Omega leader instead of Inquisitor. I would see if you could give him Expertese as that and FCS *almost* gives you perfect odds at landing every hit. I give him a shield upgrade as well to trigger his ability one or two more times before he dies... and he should be the first to go.
