NiMH have a higher self discharge, don't tolerate mis-use, and can only be
peak detect charged with advanced chargers. Since there are NiCd AA's
rated at almost 1000mah, there is not much reason to use NiMH cells.

For a AA, 10A tops for some of the newer cells and they'll get pretty
hot. 5A is a lot safer.

Because for most applications they are better.
