This is for a niche function: you want to remote into a Mac from your Windows box. 99% of the material I found on the web was some flavor of "Get a VNC client like RealVNC and use OS X's native VNC support." The problem with this, as you've surely found if you found this post, is that VNC performs atrociously. It really performs no better than a service like LogMeIn, even locally, and VNC drops constantly.
I never found anything that works as well as Windows Remote Desktop, but the closest thing I found was Splashtop. I installed the free streamer on my Mac and the free Remote Desktop client on my PC, and I linked both pieces of software to a gmail account. It's crushing VNC's performance.
