Many people just love the Mustang and Sally because of PhD Flopper in Black Ops, when in reality, any explosive weapon can fill a similar, if not better, role. The Mustang and Sally is by far the easiest explosive weapon to obtain in Zombies, but it just burns through ammo. The Ray Gun doesn't do that, because its damage makes you control it a bit more, and you have a lot of ammo at your disposal. A 40 round magazine at less than 400 RPM is pretty hard to burn through when playing effectively.

I didn't make mention of the ACR, because I can somewhat understand its merit, as the whole TTK caveat can be fixed somewhat with Stopping Power.

The MP5K's recoil really shouldn't be a problem, as it is an SMG that is completely outclassed by the UMP45 at a distance, thanks to the higher recoil and lower damage per bullet. Seriously, if you find yourself fighting ranged combats with an SMG in MW2, you're not doing it right unless it's the UMP45. The MW2 SMG's (UMP-45 being the elephant in the room) need to be used in close quarters environments in order to not be outclassed, and actually shine.

There's quite a few accurate Assault Rifles that people can choose over the ACR 6.8: the SCAR-L is a main suspect due to how early its unlocked and its predictable recoil (plus great iron sights), the MK14 has a very low rate of fire in order to fight the recoil a bit, and the M4A1 can be pretty accurate too. Accuracy isn't a very good niche in MW3, as a lot of maps are close quarters, where players can naturally focus on other enemies when in shorter ranged combat. As such, damage is usually a key to success in that game, and with the ACR 6.8's slower TTK, it'll have a hard time holding up outside of medium ranges out.
