Nobody will give assurances I am afraid but I can give you anecdotal evidence.
I have a number of Twisted based services running in Windows environment
reliably for years.  One of them is even based on smtp.SMTPFactory.  Admittedly
it does not need to be high performance.  It listens for emails and
then dispatches
requested Scheduled Task on the batch server.

If control and logging is you main goal I would definitely recommend Twisted.

Well, it depends.
In my case sticking with Twisted worked but your situation maybe different.

  Are you are the only Python guy in the sea of .Net programmers?
  Do you have to fight political battles about technology in your office?
  Is the deadline looming?
  Do you have patience to learn "Twisted way" of programming?

Check out http://twistedmatrix.com/projects/mail/documentation/examples/emailserver.tac
for a simple example.
