"Fondly remembered" has less to do with which one is more competitively accurate or which carries more rounds. Complainers against the M16action seem to forget how the Garand action would freeze up in wintry climates.
The Garand is remembered because it was used in WWII. WWII is fondly remembered as a just cause.
The M16 is remembered for Vietnam, Grenada, Panama, Desert Storm and our current battles. They may have been (and are) just causes but they just weren't (and aren't) the same as WWII.
I like the Garand for several reasons. It's well balanced and recoil is light for that caliber round. The history of invention is in the Garand. And I met one of John Garands sons and had a nice chat about his Dad.
I like the AR15 which, isn't the same as the M16, because it gives me higher scores when I shoot service rifle competitions. As far as cleaning after each shoot. Why would you want to start a shooting competition with a green barrel?
