Reply to Denon Mixer X1600 Vs Pioneer DJM-850 which one has better or more attractive FX

I would like to hear the opinion that there is out there in the DJ world about which one of this two mixer has the prefer choice of FX. Reason being that I'm looking for a Hybrid mixer so I can use with traktor, by Hybrid I mean I can use it with/without the traktor software but it most have it own Fx. not like the traktor z2 which is very limited by itself. To be honest I believe the Denon offer one of the more crutial thing that I'm looking for and that is the capability to control traktor FX when use in midi mode. If I go with the DJM-850 I would have to get some thing like the X1 to make my work flow as I would like. So what is you opinion.
