Its the money issue, im a bit inpatient, i REALLY want a license around my 17th birthday, but, because of the cost, im probably only going to be able to get my NPPL
There won't be much difference and quite likely none.
Don't be fooled by the legal minimum hours being less for the NPPL - you'll need as many hours as you need to get your flying good enough, and for most people that's rather more than the minimum. It's not going to be rare to need more than the PPL minimum hours in order to get an NPPL, in which case you might as well take the PPL tests.
