In my experience, the only way to compare any system with such a small
difference in performance is by A/B testing. That means the two antennas
mounted close to each other with elements in line (to minimize coupling
between them) and at the same height, with a LOT of testing to average
out the effects of QSB (or by studying cluster spots).
Does 1-2 dB matter? For casual operation, no. For serious weak signal
work, when your signal is at the level of the other guy's noise, it can
matter a LOT. But anecdotal comments from owners of one antenna or the
other are hardly meaningful, and often based more on the pride of the
owner in the choice he made in buying what he bought. :) If you doubt
this statement, spend a few hours reading the archive of the email
reflector devoted to ANY manufacturer's radio.

The best I can tell is the log has about 1db to 2db less gain as
compared to other non-trapped multiband designs. 10.5dbi at 65' vs
11.4 to 12.5 dbi (depending on band).
If anyone has the M2 log or other brand log and has compared them to
traditional yagi's on short booms I'd be interested to hear your
experiences.
