Had an early US press with the Pecko cut and heard some very good things about the german 320 series remaster from the noughties, so decided to buy one in near mint to get the best out of that album and its quieter songs. Turned out the 320 I got was in worse shape than advertised, but on the other hand, my early US press was better off than I remembered.
The US is more detailed, especially in the highs, and I feel like the separation is better, too, although it sometimes feels like it lacks a bit of low-end. But the 320 is no slouch and IIRC, it's also AAA, so some care went into it for sure. It's a pretty balanced mastering job and it lacks no punch for a Zeppelin record, but at the end of the day the early press wins, IMO.
All in all, I'd say if you can't get an OG or early cut for cheap, the 320 won't leave you hanging and it's a great bang for buck.
