'Quantum suicide' is a ridiculous experiment. Suppose you tried to 
kill yourself ten times and failed. What does that prove about the 
existence of other universes?

Tegmark claims that MWI uniquely predicts that an experimenter
who attempts quantum suicide will hear ten clicks - but then says
that in most worlds, the experimenter will be dead before the tenth
attempt. What this boils down to is the assertion that *if* the
experimenter survives, they will have heard ten clicks. *All* the
interpretations agree on that.
