This was about Serato, not Djay as it has no offline rendering. 
Absolutely not in those order. I’ve tested all personally on our high end system we play out on… My hope was DJ Pro Ai would be tops, when in reality it is by a long ways, VDJ, then Serato, the Pro Ai.
The reason VDJ is better than serato(both being very close) is bass quality and the ability to use eq to bring partially in or out, as well as pad based. And this is coming from a long time Traktor guy, regularly playing out and doing large events.
