We have a legacy accounting software in FPW2.6 that has been installed many times on WTS and on Citrix by dozens of customers. The feedback we got is that Citrix is faster, simpler to set up, handles printers with less problems (Users print remotely on pre-printed forms). WTS users complain that they are disconnected more often. Citrix is more expensive, but worth the difference.

I agree with all points Martin gave.
