More like only the model 25 and 30 used an AT style bus. The rest (the majority) used MCA.
The main feature is that it's probably the best performance you are going to get (expansion wise) with a 286 based machine. Also, most software will have no problems running on it as IBM was the standard (good choice for an OS/2 box).
The main negatives?
* All the sound cards for MCA were crap
* You have to source a driver for every little bit of hardware and install it to your option disk (would have been hell in the pre-telecommunications era). You need to run the config program EVERY time you change your hardware configuration.
* You need special PS/2 RAM for some models
* No IDE on some of the earlier models & no easy way to mount drives internally
