My understanding from my pre-Samba days with Win2003 and older servers (so 
it may be out of date) is that while MS DNS has support for zone 
transfers, MS AD DCs running DNS do not support zone transfers.  That 
means if you want to mix Linux and Windows DCs and DNS servers, you must 
use BIND9_DLZ or Samba's internal DNS.  If you don't care about 
interoperability, you could probably use flat files just fine, assuming 
you don't mind the extra work (either manual DNS updates or scripting it 
yourself).

I'm not certain, but you might also lose the ability for Windows clients 
to update their own DNS entries.  Some people might consider that a plus.

It's mentioned here, as an additional step for people still on BIND 9.7:
