All these apps have strong and weak points, you should listen to demos from each and decide which you prefer yourself since it's very subjective.
Here are some demos programmed in BFD with no additional EQ or compression: https://www.platinumsamples.com/JoeBarresi.html
I own everything except Strike.
Toontrack Superior has a poor user interface, the sounds are good but flat and drab, good variety. Pitches are for the most part tuned quite low. Sample editing tightness is not great. I slightly prefer the sounds to the stock BFD sounds. There are some very nice kicks and cymbals.
Toontrack EZ Drummer is very simple to use. I think it sounds very nice (I wouldn't worry too much about it only being 16bit). For pop and rock production, the only two kits I like are the standard kit and the Nashville kit. Not a great variety at all. Sample editing is good. The midi grooves are extremely well laid out and useful. The sounds work very well for kit enhancement. You have to put up with long load times. No sample tuning.
Addictive Drums has a great user interface, with lots of sound shaping tools. The sounds are very colorful but a bit inconsistent. Sample editing is very good. Midi grooves are very nice but not quite as well laid out as EZ. One of the snares is a big favorite of mine. For some reason the kits don't seem as glued together as EZ. I don't like the kicks. Demo this one.
BFD historically never ran that well for me in RTAS, but lately with newer versions and faster Macs it does not seem to be a problem. I really don't much care for the original factory sounds. They sound very roomy and grainy and don't take EQ very well. Sample editing tightness is poor. The midi grooves are pretty good, but not as easy to use as EZ. Some of the in house expansion packs sound somewhat better and have improved tightness. The reason I like and recommend BFD is because of Rail's Platinum Samples expansion packs which are far and away the best sounding acoustic drums. Check out the Joe Barresi demos, fantastic.
Both BFD and Toontack are planning huge updates, so I have high hopes that BFD2 will be as cool an interface as AD drums.
