Reply to Midi Controller Set-up

Hey guys so I'm looking at getting a Traktor S4 soon but some of the things I want to get with it is like a midi fighter pro and a korg kaos pad quad for effects. My question is what would be a better combination in terms of having a midi controller for effects and beat juggling? Because I know that one of the midifighter pros has a beat masher mapping or something like that that does effects but I don't know if it would be better for effects than the korg. Also what do all of the different midi fighter pros do? I saw there was a beat masher, cue master, and super knob or something.
