Question for the Experts

There are occasions when recommendations are made for an HBU-44 (or maybe HBU-55) and other occasions when the DB-8e & something like a Y5-7-13 are recommended.

I'd like to understand better why one would recommend one set of antennas over another.

The HBU-44 (55) looks to be more directional than others. Does that make it better than the DB-8e in some circumstances? Even though the DB-8e has a much higher gain?

Or, to look it differently, forgetting for the moment about costs and utilizing two antennas instead of one, why would you not always recommend a DB-8e for (for example) a two edge signal at, say 20dB? Or for a two edge signal at 0dB?

Thanks!
