I see this a lot, and I get the comparison to an extent. The thing is, other than Dresden, America lost a lot of men trying very hard not to kill German civilians. All the daylight precision bombing was to hit the factories, not the cities. Now the Norden wasn't nearly as good we we advertised, but had we done the British method of nighttime bombing anything we could find we would have lost many fewer B17s and their crews.
Here is an article about our use of morality in our targeting.

Of course, we undid a lot of that with Dresden. Books I have seen have suggested pilots were unhappy about being ordered to make the Dresden attacks.
In the Pacific, we also tried precision daylight bombing, and it was an abysmal failure. The altitude made it far harder to hit the target, and no one knew of the jet stream that the B-29s could reach. Because of that added wind not being accounted for by navigators, we were lucky to find the right city. The commanding general was sacked, and LeMay came in to destroy Japanese production by any means necessary. So while we went to total destruction in Japan, we spent some time trying hard to avoid it.
