I believe that's quite the unfair comparison.

Even if the components model aren't very sophisticated, everycircuit can do full analog simulations.

If you use chrome, you can run everycircuit in-browser, then try this example: http://everycircuit.com/circuit/4709435733180416/infinite-no....

Circuitverse, as far as I can tell is just a logic simulator, which - from reading the comments - doesn't handle feedback loops.
