Troops have to do the job with what they get.
Very few had the chance to try anything else and have some valid comparation. It was either 5.56 or 7.62NATO for the vast majority. This two are both at the oposite extremities of useful modern small arms cartridges.
The Russian 7.62x39 is obsolete as well. Is rather useless to compare the 5.56 with the old russian round, since nobody is going to adopt anything with that kind of balistics or that obsolete bullet design.
Like US cared about the NATO the last two times it changed cartridge.
I think if the rest of NATO would have adopted the round they wanted the first time around (.280 British), US would have adopted the same cartridge eventually and 5.56mm would have never happened.

Especially when you have to get every country in NATO to swap at the same time too.
