> not all strategies are equally as bad

That's an important point. Also, just because a strategy exists in theory, doesn't mean that in practice any voter can confidently find that strategy (since they lack perfect information about how all the other voters intend to vote).

Also, not all "strategies" fit people's intuitive notion of "strategy", which is colored by FPTP having a really glaringly awful strategic incentive for dishonest voting.

Most cardinal systems make it difficult to vote strategically. That's actually what the difference with star and score is about. But this is also why so many in the thread are talking about monotonicity and favorite betrayer. Failing these criteria means your voting system is highly susceptible to manipulation. Essentially allowing candidates to win that shouldn't have won.
