I'd guess one of them is pretty close to a perfect sine whereas the 
other - obviously - is not.

Why not record and FFT them? If you can hear a difference in timbre, 
the FFT spectrum should tell you why. If you can hit an FFT bin dead 
center, you should get a single peak with a pure sine, and various 
extra peaks with other waveforms.
