I don't know that I totally agree with your premise in the first place since the Acerbis is different than the Aerostitch in both intent and execution - but I like the Acerbis better. Aerostitch suits are wonderful garments in every way but there are other things out there that work as well and in this case, better for a wide variety of on and offroad uses. I have ridden many thousands of miles in rain, snow, mud, blistering heat, wind, in highly abrasive environments, and have yet to find the conditions in which this combo let me down. THe stuff is comfortable, bulletproof, exceptionally well-armored and relatively inexpensive. I just don't know what more one could ask from the point of function..
About the only thing that Aerostitch suits I've worn have on the Matrix combo is that they sure look *****in'
