When to use Observable.FromEventPattern rather than Observable.FromEvent?

var msgConsumer = _session.CreateConsumer(responseQueue);

"Use FromEvent for events structurally don't look like a .NET event pattern (i.e. not based on sender, event args), and use FromEventPattern for the pattern-based ones." - Bart De Smet (Rx team)
