I have a couple of P64s and I've owned Walther PPs, PPKs, and one PPK/s in the past.
The P64s don't even come close to the Walthers.
People don't like to be meddled with. We tell them what to do, what to think, don't run, don't walk. We're in their homes and in their heads and we haven't the right. We're meddlesome.
