What are the best X Servers for Windows? There are a lot out there and I'm sure they all have their different strong points. Are any of the commercial products' strong points strong enough to make paying for one a reasonable choice over using one of the various free ones, like Xming, Cygwin/X, and WeirdX?
All I really want is a plain X server. I, like most of you, I'm sure, don't need all the crud that frequently comes with them, like autologins to remote systems, xdmcp sessions, etc. They are usually awful and using PuTTY works better in most, if not all, cases.
So what products do you use and what do you see as their shortcomings and strengths?
