Despite my background in color science, I find RGB more intuitive. With HSV I have to remember the chirality of hue and it's zero point, and when changing hue I find it difficult to reason about saturation. In practice this means I must "nudge and judge" with both systems. With RGB I can always make progress. With HSV I guess hue wrong about half the time. I could probably improve this.

To be fair, I'm also colorblind. That's probably relevant.

Anyway, I'd say the answer to both your questions is: "sometimes"
