Well, Thank you all for all your awesome imput
I decided to go with a MAC tools impact with a 1/2 inch drive, and an addaptor extenssion down to 3/8 to fit all my sockets, knowing that guns get weaker in time, I rather have a strongger gun
Not to mention I totally understand about the final torque by hand, but my concern is taking them off, it does get old when you do it a lot, so I just rather hit it with the gun and have them come right off.
Thank you all, FastFreddy.
