Reply to Ecler nuo 4 or xone 42

Trying to decide which 4 cahnnel mixer to buy next, and ive narrowed it down to these two really, or is there more 4 channel mixers you guys would reccommend? (also how do the FX on a nuo 4 work? there is no fx select so is it via midi to traktor?)
Ive always had bad experiences with pioneer gear so i tend to steer clear of it.

Im planning on using decks A and B with Traktor, then have a seperate laptop running maschine into Deck C (can i do this via midi clock?)
