You simply must look at the Seecamp before you make a decision.
The Seecamp is, IMO, significantly lighter and smaller than the NAA. Remember, with carry guns, pocket guns in particular, every ounce and millimeter matters.
The Seecamp is generally considered to be the all-around better gun; better fit and finish, more reliable, smaller and lighter, etc.
As far as caliber, there was a thread on .32 vs. .380 recently:

The consensus was that the difference is marginal at best.
Someone on GT is selling both a .380 and .32 Seecamp, both NIB. Pretty good prices too, especially considering that .380 Seecamp is as common as chicken's teeth.
One other potentially major difference between the NAA & Seecamp is the mag release position; the NAA has the traditional button, same as other autos, the Seecamp has its release on the butt.
This could be a big issue because some have reported that mags accidentally get ejected on pocket guns with the traditional button release.
This is pretty much a non-issue on the Seecamp with its release.
How common this problem is, I'm not sure, but it definitely warrants further research.
I'll close by saying that I have a Seecamp and am thrilled with it. I handled a NAA first, and after doing so, was very glad I had the option of getting a Seecamp.
Don't get me wrong; the NAA is a fine little pocket rocket, but the Seecamp is just better.
