Help Choosing board, NSP or 7s Superfish.

Hello everybody, I am new to surfing and am seeking some advice on which surfboard to buy.
To answer any questions I live in New Zealand, Surrounded by water in a town of 600, heck I even
catch a boat to school. I am a very experienced body boarder and wave skier.
I will have constant access to the beach (5min walk, choice of 3 bays).
I am 5 foot 7 and 100 pounds or 45kg's, I am a strong ocean swimmer and know how to identify rips, sand bars e.t.c. I am looking to either buy a 6'4 7s super fish, or a 6'8 NSP funboard,
would either of these boards be suitable for me?
