It's a simple matter of what you want it to do.  You can't do printing
with Samba4, and the file server is best used for just the AD shares,
but on the plus side you get an AD server, and a smooth migration path
from AD (you can't migrate AD to Samba3 without rejoining machines, and
the loss of AD features). 

You can of course try the direct W2K migration - the issue that is know
won't be a silly, un-noticed bug, it will either work or not.
