It seems to me that Approval Voting might have the unintended negative consequence of electing a joke candidate, since you do not rank your choices nor are you limited to how many you can choose. Unfortunately, many voters would not give a second thought to ticking "Mickey Mouse" or similar in addition to their main choice and alternates, since there is no tradeoff involved. Under IRV or Ranked Choice, few voters would likely rank the joke candidate high.
