I don't think IRV is worse than first-past-the-post (FPTP) at all. IRV eliminates vote splitting, reduces strategic voting, and results in fewer wasted votes. Also, the fact that IRV ignores all rankings except the first until the first is eliminated means that you won't hurt your most preferred candidate by changing the order of your other preferences. If you're voting A>B>C, then if A wins, then you wouldn't really care whether you helped B win or not.
Approval voting has the problem of electing a candidate that's acceptable instead of one who the majority actually likes.
Also, IRV has a greater tendency to elect the Condorcet winner when compared to FPTP.
Every voting system has its problems but IRV is still a lot better than FPTP.
