TM hands down, Ive handled both, worked in both, TM all the way, much better. The G&Gs are nice looking, but the bolt only retracts half way, why, who knows. Also, the system for locking the mags in is retardly annoying, you've got to fiddle with it until it looks in. Though the G&Gs have a wicket system for the motor, it pivots which makes it way easier to remove the action/mechbox from the stock.
