Does anyone have any experience with WebSim Hockey?

The simulation league that I have been in for 15+ years and that has been running for 18 years is thinking about moving to this website from the Simon T Hockey Simulator that we currently use. I am trying to figure out if this is a good idea or not and figured with all the hockey minds on these forums, there must someone who can give me their opinion on it.

Looking for any thoughts that you have on the WebSim Hockey experience.

Thank you.
