When i was getting my PPL i done the same reasearch as yourself. Ended up with NFC.
The simply reason was the availablity of various aircrafts and numerous instructors.
At later stage if you decide to stay PPL level, you will want to hire planes and go flying.( unless you have your own plane)
With NFC this wont be a problem as they have loads of C152/172`s available and you can hire them pretty much any time you want, as you will find that with other two school that wont be as easy due to limited aircraft availabilty.
On other hand if you do your ppl elsewhere but wish to hire planes from nfc, you will have to do ex amount of hours with an instructor before they let you fly their planes.
Thats just my opinion and personal experience, nothing against other two schools.
