Pioneer DJMs have dozens of FX combinations to aid with fast/fancy transitions, whereas techno/trance (and similar) genres that rely on long smooth blends like the extra EQ channel and filters.

I don't know any hip-hop DJs that use Xones?

The Xones are also analogue vs digital Pioneer mixers which also plays a part in audio quality, especially if the source is analogue (vinyl, rack modules, etc).

I'm happy with my Pioneer DJM-750mk2... but also happy to exchange a kidney for Xone:96 :-)

Two CDJs cost less than weekend’s worth of personnel for a small club even.

If you’re a DJ that’s just starting out, it suck’s a little though. Usually you’ll start out on Native Instruments’ Traktor S2/S4 or Pioneer’s cheaper DDJ, and for your first club set you arrive early so you can familiarize yourself with the quirks of the CDJs. Or find a buddy with a CDJ home setup that you can practice on.

Today you also have influencers which are DJ-ing, but they don't have the skills, so either they have a pre-recorded mix or just use the CDJ auto-mixing features. Having a standard device they know how to operate is again critical.
