I don't know how true that would be in the real world, but I know it would probably be the main objection to AV. That your second (or third, or fourth) preferred candidate got to win, instead of your first. Where, you, I guess is the majority here. As I'm sure the winner in any system likely isn't anywhere close to the favorite of those who lost. For RCV, the main objection is probably that it's more complicated. Then again, Americans use stuff like electoral college, and superdelegates, and caucuses, and coin flips, to decide elections, and in comparison to all of that, the RCV system seems easy (just rank candidates in order of preference). So RCV probably has the "easy" objection between the two.
