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:
