I have tried several VNC variants and they all have some minor or not so minor issues. Depending on your requirements "the best" could be different.

If you want the most seamless experience and work a lot remotely, RealVNC is the best in my opinion. It handles keys in most intuitive way and the screen updates, although slow, are always accurate. It probably is not so good over slow connections but I have little experience with slow connections. Unix variant in my opinion is perfect in all respects.

UltraVNC has the fastest screen update speed. It is very much comparable with running XVnc on linux and windows remote desktop. The "ultra" encoding does not work really well but other encodings are OK. It messes up colors when palette is reduced to 256 colors and below. UltraVNC has more features like file transfer and chat. Personally I do not use these features. If you are securing your connection using ssh you probably want to use other tools.

I have tried TightVnc before and on linux it was OK but on windows it was pretty buggy. I need to get my work done so basically TightVnc was dismissed. It may have improved since.

My current setup consists of UltraVNC server with mirror driver and RealVNC viewer. Although colors are incorrect I like the responsiveness of emacs. Even cursor blinking is transmitted. I like the ability of the RealVNC client to transmit special keys like Alt+Tab and windows keys to the server. UltraVNC sever passes keys correctly but viewer cant capture them yet.

In the future, when mirror driver support will be available in the EE of RealVNC it will by my pick but for now it is a combination of the two.


Thanks,
Alex

Have been trying TightVNC but having had a quick look at UltraVNC it looks
appealing. Looks like a bit nicer interface and some other advantages such
as chat, and rescaling viewer to fit window. And did I read somewhere that
it's normally faster? (I just need for between Windows PCs).
Can anyone advise what are the other pros and cons between the two programs
and which is best choice overall. Many thanks. _______________________________________________
