There was a study done several years ago on the holding power between
cleats(powernail type) and staples (commonly used by the Bostich
pneumatic). I refer to those nailers because they are the dominant names in
the trade. The Canadian nailer escapes my memory right now but also uses
the cleats.
Anyway, this study, paid for by one of the manufacturers, showed that
staples hold better initially, but the GOOD cleats hold stronger longer,
especially after repeated moisture cycles.

The staples holding power is derived from glue and the slight cross angle
of the two staple legs. Once the wood expands/contracts a few times, the
glue loses bond, giving the cleated l-nail the edge.

There are some cheap cleats out there, imports with little actual cleat.
Pay the money and buy the quality ones. I prefer Powernal cleats over the
Canadian company.

That said, I have used staples over the years and those floors are still
there. I did however take the opportunity to change my Bostich pneumatic to
a cleat head, courtesy of that Canadian company(my apologies) who sold the
conversion for $80. I happen to prefer the ease of use of the cleats, and
the luxury of air, but did not like the clumkyness of the canadian
companies nailer. I tried the new-at-that-time pneumatic Powernailer, and
it was $600 worth of scrap metal(imo).

Truth be told, stay in shape and the old manual powernailer is just as
effective. I will never sell mine.
