After 40 plus years in broadcast engineering I can assure you it is =

judge the performance of *anything* by it's spec sheet or sales =
brochure.
Direct comparison under identical test conditions is the *only* way to =

which device works best.

The LG had the correct combination of specs that finally
met what was needed there. For example, evidently 0 dB
echo tolerance was not of paramount importance, whereas
something else, like perhaps echo tolerance at -10 dB,
or the IM3 performance, or other such, are far more
critical in that location.

Now take the guy trying to receive a station from way
out there in the sticks. I would expect the -84 dBm
sensitivity of the Samsung would perhaps serve him a lot
better than the LG's -76 dBm.
