Agree have never had problems with either NiCd or NiMH.

I beg to differ. I have had NiCd and NiMH cells leak. The difference
is that unlike alkaline, they don't leak in the package:

I've found from dealing with commercial walkie-talkie batteries, that
if I leave the packs totally discharged for more than a few weeks, the
batteries will leak. The good news is that this rarely happens.

I've had several NiCds & NiMHs leak, but way less often and far less quantity than primary cells. Usually there's no significant damage to the battery holder.
