can anyone tell me the difference between Empire Zoysia vs. Zeon Zoysia (grass, spring)

Can anyone tell me the difference between Empire and Zeon Zoysia sod? We are thinking of redo our lawn. But we can't decide which to take. The thing I care the most is

1. Maintenance cost ( I need to water less and mow less :-) I am lazy, I know :-))

2. Appearance. I heard that Zeon turns green later in spring and turns yellow earlier in fall.


Anything else? Any suggestion will be greatly appreciated. Thanks all!

Looks like Empire grows a little faster to cover:

Empire has broader leaves.

As I have considered zoysia cultivars, I know that I want:
1. Best in shade.
2. Good cold tolerance and early and late year green.
3. Finer leaf blades to emulate some cold climate grasses.
