It is intrinsically very hard to be the best at everything - someone who specializes will always be better than a generalist. The only nation I know of to manage to have the most modern industries in essentially every field simultaneously were the British - briefly - but that had to go away as soon as other countries kicked off their own industrial revolutions.
Also worth noting, of course, is that countries develop their own ways of doing things. OTL for example Rolls-Royce Merlins were built with parts binned by the micrometer - that is, they would measure everything and then use the in-spec but slightly small piston caps on the in-spec but slightly small pistons, and so on.
Merlins built in the USA had to be built with much tighter tolerances, so their output rate was actually less when normalized to the cost of the machine tools and so on - getting the precision the Packard Merlins needed was much more costly in tooling.
Now, of those, which is superior?
Neither. Both produce very high performance engines using the tools and men on hand. The tradeoff is cost based.
