Just my personal point of view.
Despite having the same overall length to the AUG commando, the SIG has collapsible stock as it uses AR18 system rather than AR15, which doesn't have a back buffer. Therefore, it is shorter when folded and you have an adjustable stock for comfort, which is a short coming of the AUG. Also, adjustable stock to compensate for the gear thickness is a real thing, especially with magnificated sight or scope.
At least you guys are getting more toys. Canadian Army is still playing with full size AR15 and WW2 era handgun, which even the stubborn USMC has dropped.
