Actually, the biggest thing Quasar gives you is lightweight threads. That's the hard part. Building actors, agents or dataflow variables on top of that is very easy.

Having said that, I do think actors have some advantages over agents when it comes to fault tolerance. Actors better isolate and communicate faults.

Yes, you are entirely correct, my point about actors vs agents was only taking in consideration a shared memory situation (only one local multicore processor), in case of a distributed system with multiple nodes located on different memory spaces and machines the erlang approach is much superior, especially for actor discovery, monitoring (ie heartbeat) and fault tolerance in general.
