Not to suggest that anyone will change anything about what their 
favorite platforms are, but since you raised the question...
Some things are actually simpler with a Windows host system running 
a simh simulator with Ethernet connectivity.  Specifically, to achieve 
TCP/IP connectivity between the host system and a OS running within 
a simh simulator on that Windows box, there are absolutely no extra 
steps.  It just works.

Most/all Unix or Unix like operating systems have significant 
potentially complicated extra steps to achieve such communications.

Sure, often direct communications may not be necessary since much 
access can be achieved via telnet talking to the simulated system's 
simulated serial ports, but that just side steps the problem.
