Default Re: White Balance or Exposure Set First?

First WB then exposure.

Exposure quality itself will benefit from proper exposure across the spectral frequencies in the image. This means that it will pay off to color balance to the dominant lightsource (!) -or more correctly "illuminant"- first.

In the old days the best way to achieve this was by using proper filters on the lens, to match the scene's color balance to the sensor's sensitivity. This will allow to expose the R/G/B channels to "the right" and achieve a high Signal to Noise (S/N) ratio.
