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... :-)

In the famous HBR receiver design by sk W6TC, the product detector was a
6BE6 in the original circuit, but he later changed it to use the 6BY6
claiming that it gave better performance with less cross modulation and
overload.
