I live in Switzerland and in my anecdotal experience with only a few samples of each (which is not statistically valid but affects my immediate perception nonetheless), Amtrak has been somewhere around as punctual as Deutsche Bahn including on Amtrak's longer routes. The long-distance Amtrak routes also have far more comfortable rolling stock, but that's only natural for a 10+ hour route.

I once took a Czech train which was perfectly on time to connect with a German train which was delayed enough that I'd miss my next German train, except that delay ended up not mattering because the second German train was also delayed, but then the second train was completely canceled so I ended up waiting in a random city to be rerouted on completely different trains.

I'm sure DB is better than Amtrak in general, but the current state of DB is much more pathetic to me given its better performance in the past (AFAIK, tried to find data on this). The infrastructure and political will seem to exist to do better, which isn't generally the case with Amtrak, so it seems less excusable to me.
