CDJ 2000 or 850 for Cross

Hi - I'm a newish user (managed to map my XDJ-AERO to use Cross at a basic level on 2 channels which I'm enjoying), but I'm looking towards the future now and hoping to get a pair of CDJs to use with my old Ecler Nuo 5 mixer (looking to get a DJM eventually).
My question is, how well does Cross work with the various Pioneer CDJs (I'm looking at getting a pair of 2000s second hand or new 850s)?
I know pretty well how the cdjs perform when just using rekordbox (which will be about half my gigs), but when using my laptop and the Cross supplied mappings, are the CDJs about the same or is there still a lot of extra features the 2000s have over the 850s ? I'm guessing the 850's beat slice buttons are used for samples/hotcues.
Hope someone who's used either or both with Cross can give me some pointers. Thanks for any info
