For Web Clients you don't need the extra server, including Microsoft licenses and the licenses for Citect Anywhere.
On the other hand Web Clients can only run in MS Internet Explorer, and all the standard Citect TCP ports have to be opened in the firewalls as well as the http/web port(s).
So you would have to consider security, costs and complexity of both implementations when choosing the right solution for your situation.
