Yes... and No
Back to the title of your OP...
A larger antenna is generally better at gathering signal from a narrow range of azimuth. If all the signals you desire to receive are within that range, you get more desired signal while getting less interfering signal from other directions. In this scenario, the big antenna is 'best'.
Small antennas generally have less ability to gather signal and they tend to be able to receive from a wider range of azimuth. In some situations (ex. the desired signals are strong and widely dispersed.) the smaller antenna is 'best'.
In situations were there is a mix of strong and weak signals, the antenna(s) need to be large enough to receive the weakest signal. That can make the antenna forward beam (range of azimuth) too narrow to receive all available signals if the stations are scattered around the compass. Multiple antennas or a rotator may be needed in such cases.
So the best antenna for you is not necessarily the best for someone else.
