I would go towards Zeon. Less tendency to get thatchy and lumpy like Emerald. Emerald is hardier, but you really need to maintain Emerald as low as possible

At least in Hawaii, Emerald Zoysia is the grass for people that kill other grasses. That is how hardy it is. Only disease issue I have seen on it is Dollar Spot vs the other cultivars getting bad Large Patch.

I want to say 40% as hardy. It is really sensitive to certain herbicides, is picky about its height of cut, yet it wants to grow 2" in one week and it is incredibly hard to mow. Only way I can live with Zeon is to limit water and fertilizer then go extremely heavy on the PGR.

Avoid Sulfentrazone on it. Do not apply more than the lower rates of Quicksilver either.

A conventional Pre like Prodiamine, Dithiopyr, or Pendimethalin will not control those weeds anyway. But, Zeon will tolerate those Pre herbicides well. Root pruning is not as much of an issue on established Zoysia vs other warm season grasses.

When you mention limit the water, what exactly do you mean?

I keep it on the verge of wilt. Not doing that gives me a lawn that is difficult to keep up with mowing on.
