Recoil is a pretty big selling point for me. When its between a $800 scorpion and a $1500 banshee sure get the half price scorp, its a no-brainer unless you really hate recoil or are looking for a more refined shooting experience. But now with the a3, the price is so close I wouldn't consider the scorpion(any blow back 9mm for > $500) for a second. $450 extar.... you bet

But maybe shooting a jackhammer is your thing, go for it! I have a gun for these situations it's an 8-inch psa ks47 with a griffin paladin muzzle break, punches you in the face every time you shoot it. Its the only gun I like to you shoot unsurpressed and it bucks like a mule... I f*ing love it. But when I want to run down steel plate racks or beat my buddy at the dueling tree gimmie that radial delayed 9mm goodness ;)
