The original spywatch is way better. Sure, you can take the cloak & dagger, camp in a corner for fifteen minutes and kill a few targets but the VERY slow recharge of cloak, the fact that you can't charge it with ammo and the VERY quick depletion spoils it all.
cloak and dagger is fun if you want to play a bit more stealthily, but I find myself being less helpful to the team in general. I like how stepping off a ledge drains it all entirely from the speed of your fall
