I tried both in tfb and s&v and with max crit and surge tactics is far better then assault. I just seem to crit a lot more in my rotation and it seems assault relys too much on a proc, crit ,hib . Tactics has more abilities that crit more especially a free crit hib. and no ammo stockstrike. My flame pulse crits for about 6k im not sure if ap can do that....
