I have AD2, EZdrummer 2 with some expansions, and Superior drummer 3. Honestly, the more advanced the VST is, the better it'll be on the computer. But when you are exporting only 2 channels in a multi layer sample to play on the 2Box, you don't need to expand that much on VST...
EZD2 (and expansions) for me is the best to export on 2box - and it's the cheaper at the same time! The only thing is that most of them don't have 3 zone cymbals, but other than that, I usually get amazing results out of the box just using their pre-set.
