Reply to Upgrading my DJ mixer, need quick help choosing between 2!

I'm in the process o selling my CDJs and switching to all digital on Traktor and MBP, and I'm currently using a Pioneer DJM500, with only has 3 line inputs so I can't use all 4 Traktor decks, which is why in selling my decks to get a new mixer.

I'm choosing between the Pioneer DJM 800, I love it and have used it a lot, has 4 LINE inputs so that's fine for me, but also, there's the Allen & Heath Xone92 mixer, which I watched a video of 'How I Play - Chris Liebing' uses, and it seems cool, he has routed his Maschine somehow into it without taking up any of the 4 channels. Which is something I need as I have currently routed Maschine as a live input into a Traktor deck and the 3rd channel on my mixer,

Leaving me with only being able to use 2 Traktor decks

So, what shall I get, will I benefit from getting the Xone92, being able to use all 4 Traktor decks AND having Maschine
Coming out of another channel (aux or something? I don't know much about this aux/send&return)


Or can I do this with the DJM800? As I've had an offer to swap my CDJs for someone's DJM800.


Thanks.
