NOLO, the AK was never fielded against the Garand in any meaningful way. The Garand, by the way, was issued half a decade before the SVT-38, and was a general issue weapon unlike the SVT-38 or SVT-40 or any of the German weapons.
Also, the AK excelled in one area only, high fire-power at medium/short distance, compromised my mediocre accuracy. As brighton noted, at long distances, men armed only with AK's would be at a severe disadvantage to men armed with Garands. So, the AK works in some scenarios, like building clearing, but not so well in others, like across a field where the Garand's accuracy will more than make up for merely 8 shots.
Yet, the Garand excelled in every way over contemporaries. It was faster to fire, faster to reload, and maintained the same if not better accuracy. While the Enfield carried 2 more rounds and so allowed more shots between reloads, it was still slower to fire for the average Brit and slower to reload with a two-step operation (two chargers to get to 10 rounds, one charger only getting you 5 rounds).
The Garand was in general use for 20 years. Consider the Soviets replaced the AKM after 25 years with the AK-74, you realize that terms of use, the AK-74 has had a longer general issue with its mother country than the close cousin. Semantics? Probably, as they are both very certainly the children of Kalashnikov. But the M14 is the child of Garand, then we can add those two together, too, and you get a service life about as long as any other standard shoulder arm in US service.
Is the Garand obsolete today? Sure. Is the AK? Not at all. That is not the point nor has it been. But the limited issue of self-loaders by the Germans and Soviets (and even Japanese) does not equate with the fact that, beyond snipers, every single soldier in the US Army in WWII, whether infantry or cook, began the war with a self-loading weapon. The infantry carried a Garand, and while it alone could not win a war without subguns, grenades, artillery, air support, rapid mobile transport, and the tank, as a general-issue infantry weapon, it stood alone against all the competition in WWII, throughout the entire war because no other nation reached half self-loader issue, much less 100% (beyond snipers, of course). And in any case, in places like Normandy, the Sigfried line, the Battle of the Bulge or Italy, there were many places where the action was settled by man-on-man. In that instance, the Garand was vastly better.
But the Mauser was certainly not so significantly better than the Enfield or Mosin to be much of a difference. The Mosin and Mauser have roughly the same rate of fire and magazine capacity, the Enfield having twice as much capacity and a somewhat quicker bolt-throw but slower reloading to return to the ten rounds (same reloading to keep 5, though). Bolt actions compared with bolt actions you still have bolt actions, with bolt-action speed and bolt-action capacity.
