My mileage did indeed vary.
I had an old 14AVQ mounted as a ground-plane up about 35' and it was a
killer DX antenna, not as good as my TH-6DXX at 75' but very good as a
second antenna. I later mounted it on the ground and it lost a lot compared
to the TH-6DXX.
As a GP on 40M it was a great antenna for DX work. On the ground, it was
less than a dipole at 50'.
As you said YMMV
