I have played with them, but that was almost 15 years ago. The only
thing I remember was that the VCO drifted a lot. As can be seen from
the design equations, the transconductance is heavily dependent on
temperature, even without an exponential converter.
For serious VCOs I'd recommend the Electronotes designs, or discrete
types such as those in the Odyssey, SEM or Prodigy.
