Is there any obvious choice in 6BY6 vs 6BE6 in a product detector?

I've subbed one for the other in replacement uses and there wasn't any
hugely obvious differences, but maybe if someone told me what to look
for... :-)


Hallicrafters used a 6BY6 product detector
in their highly regarded SX-115 receiver.
Interestingly, they included a 3.3 ohm 1 Watt series resistor
in the 6.3V heater supply for that tube.
