What we tested was the actual DC mV on a dual diode peak detector vs RF mV in. I forget what the the frequency was. The 1N60 performed to lower signal levels than a 1N5819 HP Schottky signal diode, which is also seriously more expensive. It was a proper lab at work. We mostly tested currently available stocks so no valve based detectors of any kind. We did include some old Ge diodes I have and some freshly purchased OA47 (which was poor actually). It was for an actual product, so it was really a choice between the 1N60 (still made), 1N4148 and a small signal Schottky sold for RF and switching applications.
I think for general use the 1N4148 is best.
For low level RF, like RSSI, Forward & Reverse HF power meter, AM radio detector etc, the 1N60 wins.
The Schottky diodes more for high speed switching applications and some specialist RF, though for RF switches a PIN diode is better.
