There is some scuttlebutt that the plane is a widowmaker, but I don't
know the reason, though an acquaintance of mine died in one. I believe
the NTSB decided that he mismanaged the fuel transfer while flying an
instrument approach in snow, which may have nothing to do with the
flying characteristics.

I think it depends how much you fly it. A twin requires an extra layer
of competence, apart from double the engine maintenance cost.
Remember, if you lose an engine on takeoff and are not current in
engine-out procedures, the second engine will just take you to the
scene of the crash.
