Reply to Denon SC2000 vs A&H Xone:1D

So my faithful Feena controller is starting to, well, be a little less faithful. It's faced almost 5 years of at least weekly gigging, so I like to believe I got my money's worth.
So I'm tossing a couple things around in my head, one of which being picking up a pair of SC2000s or Xone:1ds, and go to an external mixer set up instead of using Traktor's mixer.
So, as I've not yet had the opportunity to put my hands on either of these, I'm looking for input.

(the other couple things I'm looking at is the Kontrol S4 and the MC6000, but that's a whole other comparison thread lol)
