I recently discovered that the Yamaha PSR-740 has both a "Sine Wave"
voice and a "Thick Sine" voice. There is a big difference between
the two, yet you can tell that they're both using sine waves. So
that's my empirical experience of what is "thicker".
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.

What is
thicker?
Now, that is probably very subjective, but in general, it would be
a sound with more information in it. For example, some sounds are
improved by adding slightly detuned oscillators in large numbers.
(Well, most sounds, if you're into "organic" or analog/acoustic
feel sounds in general.)
