DJM 2000 with denon platters

Hey I am about to purchase a DJM 2000 mixer and was planning on getting denon DN-S3700 decks to go along with serato SL4.

the question i been wondering is what are the benefits i would get in going with the CDJ 2000's instead? I know that they are clearly meant to go together but aside from the flashing lights what is it that would be an incentive for me to buy the cdj2000s instead? I heard that they were integrated together for a reason. what reason? im getting denons simply because i prefer the direct drive platters as well as the cheaper price. but if there is a good enough incentive id go with the CDJs if it is worthwhile.

also is there any connection issues that i may incounter while going with denons?
