Not really, only thing the snap on has is that it's faster and has some sort of anvil brake.everything else the Milwaukee can do.the milwakee is one inch shorter and smaller in diameter, but feels like cheep plastic.i personally like how strong and solid the snapon one feels, like if I manually torque with the Milwaukee I can feel the battery flexing.doing that with the snap on it feels solid and can give it a good torque but the ratchet head on the snappy feels sloppy like its a low tooth count and I need room for a bigger swing angle to grab another tooth compared to the Milwaukee.also the battery doesn't seem to last as long as the Milwaukee but charges fast.and the snappy is a bit heavyer.
Lately besides a few trigger issues on the ct8810s, snap on cordless has been getting better.but still only offer one year warranty on tool and battery where as Milwaukee is 5yr tool and 2yr battery warranty.the only problem I have seen with the m12 ratchet is my Forman has broken the square drive heads on both of his,and both have been warranty repaired by a local authorized repair facility.
The only reason I use my snap on now is because I like how it feels and the speed it has, also my girlfriend went out and wasted her money for a green tool for me.so I want to make sure it's not wasted........if she hadn't gifted it to me, I would never gone on the truck and bought one.
