Your probably better off getting samples for good sounding acoustic drums as far as electronic drums go try either tremor by fxpansion or rob papen punch. also check out maschine its software and hardware combined.
I really like Izotope iDrums, for people using Cubase, Logic or even Pro Tools who want that FL way of building drum patterns iDrums is the best option...There is a swing option and volume etc. However there is a limited amount of drum sounds that come with the program.
