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... :-)

The 6BY6 was intended as a sync separator, and to run with 10V on the plate
at that voltage. My bet is the 6BE6 would be the better tube to use unless
your PD is running at reduced plate voltage.

Can the 6BY6 be used as a converter? The whole thing about the 6BE6 is
that changes in control grid voltage don't affect the cathode current much.
If you're doing the self-excited oscillator trick, I think you need the
6BE6.

In my case there's no desire for using the tube as an oscillator.

I was just doing a survey of my radios yesterday and the number of
6BE6's stuck in sockets labeled 6BY6 was astonishing :-).

Some discussions in the ham literature indicate that the 6BY6 is less
prone to overload.
