Terminal Server VS Citrix

Is there anybody out there that has been on a Windows Terminal 2003
server farm and then switch to a Citrix Presentation Server Farm? How
was the comparison? Any pros and cons that I should know about? Your
input will be valuable into my research of a server farm.

We are currently on Vantage 6.1 on a Windows 2003 server with approx.
70 local users and 32 remote users on a Windows 2003 Terminal Server.
We will be switching to Vantage 8.03.400 in the near future with about
the same amount of users. We could see about 10 more remote users being
added in the next 6 months.
