I had two HDS lights and was sorely disappointed with both experiences. So-much-so, I gave my second one away - with no regret.
In my limited experience, for the same hourglass shape, you can get soo much more (colors, emitters, materials, output, UI) as-well-as on par fit and finish; with a KR4. Consider that the secondary LEDs of the KR4, alone, have more functions than the entire UI of any HDS.
But, get what makes you happy. And, let the group know what you decided.
