Which antenna is more efficient?
A vertical of a 1/2 wave-length that resonates at the transmitted 40m frequency,
A vertical of 32feet with a tuner at its base adjusted for VSWR of 1,1 at the same 40m frequency?

All other parameters are the same for both. Ignore any loss in the tuner.

If we ignore tuner (and feedline) loss, then both systems are 100% efficient. They will have different radiation patterns, of course. Perhaps I misunderstood your question?
