freeNX vs X2Go

While trouble-shooting FreeNX for 12.3 x64, I came across X2Go. Is there any community opinion on these two? I noticed that FreeNX is not really being updated, whereas X2Go seems to be in active development. (I believe they are both implementations using NX and OpenSSH.)

Can anyone share experiences? I need to give users KDE across an NX layer.

Thank You!!
