It should sound the same and look the same spectrally.  There was a
previous discussion on the list about how noise distributions (uniform
vs gaussian pdfs) should sound.  Namely, the same :)

To see the difference, you could try to calculate kurtosis values!
I've never had a good use for that one.

That statistic will show you the difference between Gaussian and
uniformly distributed noise, and confirm your distribution.

The Box Muller method should be good--that's a very reliable method.
