massively different contexts
the germans were up against 2 out of 3 of the top 3 navies at the time
they were literally building ships faster than the germans could sink them, once the americans joined in the germans needed to sink 400k tons of ships to win the tonnage war, they only achieved that goal once
and after 1943, allied ASW ramped up in intensity and contained the U-boat threat
the japanese didnt put much thought into convoy protection or ASW, and lack of industry meant that they couldnt implement good solutions even if they wanted
germans had to climb a mountain the allies had to climb a hill
even with a huge headstart, victory was never assured, and the allies ended up making the mountain taller just for good measure
the allies just had to do less work to win while the japanese ended up putting ladders down just for good measure
