I suggest that Instant Pairwise Elimination provides a great balance
among these requirements.
1: It's simple to use, and simple to understand how to count.
2: Rarely could a voter identify a situation where their vote was wasted.
3: It's not a Condorcet method, yet it would be very rare for it to
elect a non-Condorcet winner.
4: Tactical voting is possible, but only when a rock-paper-scissors
cycle is involved AND involves the most popular candidates.
As a reminder of Instant Pairwise Elimination, it's described here:
