Keep in mind that if you choose another option such as VST for your drums, you're still using the T2 styles. If the styles lack the "dynamics" then sure using the VST's will sound better, but you still will not get the dynamics.

I think overall the T2s drums aren't bad, I've surely heard worse too. I think the problem as I found on "EVERY" Yamaha arranger I've seen to date is that the drum tracks in the styles are lifeless because they lack "dynamics". You can have the greatest samples in the world, but if the drum track is weak on the dynamics the best drum samples can sound poor.
