I vote for 1 second rounds. Limit everyone to one action a round. Complex tasks like using a bow or casting a spell take multiple rounds.
This keeps players more engaged as fewer actions lead to less time between turns. It minimizes the cyclical effect of a round based system. It gets rid of the nonsense about "one attack is really 4 attempts to attack."
The biggest "problem" with it is that there will be turns where absolutely nothing exciting happens. I don't see this as a problem, but there will be those who do.
