I tried both Xming (donated and got the most recent versions) and VcXsrv. I found VcXsrv to be faster and dynamically picks up my screen resolution. Xming doesn't do that out of the box.
However, I find that both are terrible when my network is a bit unstable such as when I'm in transit. That's the major pain point I have.

I think what they mean by "no current plans to support X/GUI apps" is that WSL itself doesn't include support for an X server but you can still go ahead and connect X applications to any running X server.
It's unsupported, which means it doesn't necessarily work well and they won't help you out.
