I've been thinking some more about Bernie's point. In theory it should not, but 
in pratical operation, it does matter where the config information is coming 
from.
The ops people in charge of routers are not the same as the one in charge of 
servers (DHCP included) ... and the last thing I'd like to see hapening is the 
source address selected by a server to change if one team changes a lifetime 
without noticing the other...

I would think that how an address is assigned shouldn't enter into this.
I can't see that it matters.

What really matters is the lifetimes associated with the address. The
longest lifetime address is probably the best to use since it is the
most stable. [Ignoring privacy and other related issues.]

Perhaps this gets at what you want anyway, since manually assigned
addresses would presumable have the longest lifetime?

Except that from what others have said, that might not be the desired
goal. Perhaps for privacy or other reasons, a most stable address choice
might not be optimal.

I originally thought that would be the best choice, but ...
