Personally I think the drum options you listed are for different purposes. SD3 and BFD3 obviously have presets but also are aimed at giving the user the ability to take the raw sounds and craft their own sound from scratch. AD2 is more aimed as having a ready-to-go premixed sound to insert directly into a mix, sort of like you outsourced to a session drummer and engineer for the drum parts. Now as for which one you wind up using won't really make two s***s of a difference to the end listener. Hell you could even go against all conventional wisdom for the style of music you play and stick static electronic drum samples of a tonality that isn't normally associated with your genre and as long as the mix slaps, people will not care, not one iota. They are after all just percussive noises, intended to thump, thwack, doong or whoosh and then get out of the way of rest of the track. Whether you use a top-tier acoustic drum sampler, or record yourself hitting objects around your home, they can all be shaped to achieve a similar thing in the end.
However given what you have said in regards to raw sounds, my vote would be for BFD3. The sound of the kit samples with all fx off, is the most raw sounding. SD3 is pretty raw too when you take everything off, but it makes me feel like what I am hearing has been just a tad pre-processed/leveled, etc. In regards to the significant price and storage size differences of both products my vote would also be for BFD3. I know that all the options of SD3 might be enticing, but like all instruments you will wind up with a small amount of "go to's" and the rest will just occupy drive space. They both sound interchangeably as good when mixed, so really it may be a question of how much stuff do you want collecting virtual dust?
