It is a good start, then ask any questions here.

This is very subjective, if you ask 100 Samba users 'which is best', you 
will probably get about 150 different answers :-D

I think you mean 'Does the DC with all the FSMO roles and any other DC 
need to run the same version of Samba' , to which the answer would be:

Ideally yes, but different versions will work together, just don't try 
to use something like 4.1.x and 4.12.x together, it may work, but I 
would bet there will be problems.
