The answer is (as always): "It depends!" :-)
I've used multiple instances of MIR Pro directly on the individual elements of drum sets in the context of purely acoustic music (Jazz, Folk, Singer/Songwriter-stuff). I've also used two or three instances set to 100% wet and wide stereo in different distances as some kind of sophisticated AUX-send reverbs in Rock/Pop-mixes. ... an example from a comparable setup (not drums, though) can be seen in the 1st screenshot.
One important thing to keep in mind is that the default 50% Dry/Wet-ratio will be too wet in almost all cases. It's almost equally important to use the RoomEQ to tame boomy or overly metallic resonances. Reducing the reverb time to a length that fits the arrangement and playing-style is another quick fix that's easy to try out.
Finally, a little-known but nifty trick is to use off-center positions of one of MIR Pro's studio-venues by adjusting the rotation of the Main Microphone respectively. One of my favourite spaces for drums is the Live Room of Studio Weiler in portrait orientation, bottom-right behind the Mic, with the huge bass-trap in the corner (see 2nd screenshot).
HTH,
