If you will be using the dipole for the freq of resonance, a 1:1 will divorce the feed line from the reception pattern nicely and may provide best transfer of energy, the z the antenna sees is also nominal to the feed line. In the case where a dipole is used at freqs outside of resonance, where the z seen by the wire is very different from the z of the feed, over or under coupling might transfer more received energy and this will be freq/wire length dependent.
Odd 1/4 frequency multiples of antenna wire length should result in low feedpoint z meaning a good match for direct coax feed, evens over a halfwave should result in much higher z. A halfwave endfed has around 2k ohm z.
