I've actually found the userspace server utterly trouble free, and had 
some significant problems with the kernel one. On the other hand, I've 
only ever used the userspace server for read-only tasks (serving LTSP 
machines' root filesystems) and for that speed isn't actually a real 
issue. Once X is running, the LTSP boxes have basically everything 
they'll need loaded in RAM, and rarely need to access their remote root FS.

If things go wrong with the nfs userspace server, its much easier to fix.

That said, I've always used the kernel server on those rare occasions 
when I use nfs for read/write access (temporatily, on my home LAN, and 
only with specific IP restrictions - for when scp is just too slow).
