In practical terms the biggest downside to nearly all 'pups I've seen is that the LOP is fixed. There's no reason it would have to be but few designs seem to prioritize give the end user some adjustment. The triggers tend to be poorer but as another poster mentioned if you design the thing with electronic ignition it could be as crisp as anything on the market. Ejection can certainly be designed to toss the brass wherever you want it to go. I'm not all that interested in them, probably because I grew up shooting conventional designs, but like many guys my age I've always kind of wanted to have a Steyr AUG. I blame Die Hard for that!
