Either way - in two years time it will all change with EASA licences
I was taking too long a few years ago, so I opted for the full JAR, but after a couple of months I lost my medical - still not got it back, so it made little difference...
Look at the EASA proposals, and decide if you need the full JAR, or just a LAPL (sic) in which case go for the NPPL.
It is easy to say you want the extra, but unless you have a good budget, the cheaper route makes a lot of sense
Best of luck!
