So in what way does the full wave dipole "perform better" than a half

My 20m rotatable dipole gives ~2dB gain on 10m according
to EZNEC.


All you need to do is rotate it! That does work for your instance. But
it is a long way between your 20 meter rotatable on 10 meters and 10
meters on a 160 meter dipole. But the statement from someone that more
metal in the air rules - or something to that effect - isn't correct.

My nice antenna pattern on 80 meters is starting to look a little funny
on 40, and it gets downright weirdly lobey looking on 10 meters. Some
places it works great, and some it doesn't. No free lunch. If you add at
one place, you subtract from another.
