1-arm AGI is nice but IMO not all it's cracked up to be. No effect on movement, bad effects on anything you need to 2-hand, which is most if not all Automatics and Longarms depending on GM ruling.
Don't get me wrong it's great for a pistoleer but I can't tell you how many times high-AGI move has saved my bacon or let me set up in a better position to annihilate the opposition, and a dumpstat AGI character can't rely on that at all.
