Which Controller?

Hi,

I'm looking at purchasing a WorkBee 1500 x 1500.

The site I'm ordering from (I'm from South Africa) have the following options when it comes to controllers for this machine:
GRBLDV8825
Mach3 - 4 Axis NVUM (Need to still purchase the Mach3 license separately)
DDCS V3.1
I'm having a hard time to decide between these options. Any help would be appreciated.

Also, does the choice of spindle I'm going use influence which controller I get, or doesn't it really matter?

Thanks.
