For windows, try mobaxterm. I tried a half dozen x11 servers a few years ago, and it was the best by far.

It works great, modulo 3d acceleration. If I remember right, cut and paste work well, so that (plus a file share for Downloads) gets rid of the need to run a web browser in Linux.

Similarly, it can use the windows wm to manage the x11 windows, so you automatically bypass the linux compositor.

[edit: Also, Hyper-V is extremely fast in this type of setup, because they focus on server performance, and this workload looks like any other network/io intensive server]
