I'm running a Bmax4 III and have recently swapped from a Savox to a KO Propo RSx2 Response and I couldn't be happier with the results. I probably sounds stupid but just swapping to this servo improved my results instantly.

I too am running am running an Exzes Z setup and considered going for a Sanwa servo but in the end I went with the KO as I more people seemed to recommend the KO over the Sanwa.

I'm currently building a YZ-2 and will be running another RSx2 if I can find space for a full size servo, if not I will be running the low-profile equivalent from KO.

Hope that helps.
