If you have exactly the same zone content on both boxes, then ultimately 
it doesn't matter whether the serial numbers are the same or not. 
However, if one of the boxes is defined as slave to the other, then if 
the serial numbers aren't the same, specifically if the slave's serial 
number is less than the master's, in sequence-space arithmetic, you 
might waste some bandwidth with unnecessary zone transfers. So it's 
probably best to keep the serial numbers the same, initially.

Where it gets more interesting, of course, is when you start *changing* 
the contents of the zones...
