I've no specific knowledge of either frame as I don't do that kind of riding.
A better question might be where does a gap exist in your stable of bikes? (if you have 7 Riv's you may not have much/any gap). You cite the Hunq for the heavy loaded stuff and that you'll go load-free with no extreme riding on the Gus/Susie. That right there would steer me towards the lighter Susie. Perhaps the best question is what do you prefer: threaded or threadless? There are pros & cons of each. Do you already have a bunch of stems of one type, that might inform your decision as well as it would allow you to better dial in fit. Despite his prickly reply, I do agree with Steve that the minuscule weight difference of the headset doesn't matter.
