I think it is more than just
a couple of extra hours.
AFAIK, the JAR-PPL currently requires a minimum of 45 hours, including 25+ dual, whereas the NPPL is a minimum of 32 hours, including 22+ dual, so there is a significant reduction in the hours' requirement for an NPPL, if those are the only privileges you want.
In addition to this, of course there is the less demanding medical which you mention, so an NPPL remains a distinct advantage to those who cannot meet either the financial or medical requirements of a PPL.
