I would rate the styles as

1 Sd-1 overall winner for best mix
2 PA-80 real close to the SD-1
3-4 Roland and Yamaha, both have great styles and both have alot of sleepers, not very long either, they seem to stick to 4 bars rather than doing 8 and more which korg and ketron use

( Boy do I think I know alot, I better tell myself to shut-up )
