I can support what David says about this. I have both a 40m Telrex full-sized
single element mounted horizontal at 67 feet and a (nearly) vertical wire
dipole with the top approximately 60 feet. They are supported from the same
tower.
The majority of the time there is hardly a detectable difference in signal
strength between these two dipoles. However, there are times when a signal
simply "disappears" on one antenna or the other. The phenomenon is the same
whether it's a stateside or DX signal. There is no consistent pattern where one
antenna would always be better.
During a contest I am always switching between these two antennas as I tune the
band looking for contacts.

Subject should be 'Vertical AND Beam', or 'belt and suspenders', come to
think of it, they are horizontal and vertical as well... in any case, having
both is better than having to pick one or the other!
