As for quality standards, excessive quality in wartime production is a waste. This was normally very much the Russian approach, with high quality only applied where it was vitally necessary. After some development of the French original the Hispano worked: that's all that was needed. If the MG151 was "better" made, then it was worse made.
The Hispano´s DESIGN is utterly crude. So crude that it could not be synchronized. Perhaps the latter factor is the reason you never saw 4 fuselage mounted Hispanos in a single engines fighter...

The NR-23 had nothing that could not have been designed in the 1930s. Besides, Russians managed to put 3 ShVAK in the fuselage of a fighter with smaller wing than of the 109.

And finally, you prefer the Klimov VK-105 over the P&W R-2800? The former was certainly sufficiently badly made not to have "excessive quality" and surely is a fine example of "all that was needed".
