I think it would be nice to have a few more options listed in each category, since not all
batteries on the shorter list are always available everywhere.
After thinking about it a little bit from a safety standpoint, the division between the "high capacity" and "high power" category can be a bit irritating imo, because of the listed batteries different CDRs with a (recommended) spread of up to 13A. And the question arises, why the 25R is a high power cell, while the HG2 is "only" high capacity, although they both have the same CDR?
I'd propose to list 18650s just by power level low, medium and high.
