Well I'm just gonna copy and paste a comparison I put up on the specs of Those lights and also the Armytek Wizard Pro Warm so here you go.
From what I can see the Nitecore HC30 is only offered in Cool White which would eliminate it for me right off the bat for outdoor use. I looked up the modes for the Nitecore HC30, Zebralight H600w MkII and also the Armytek Wizard Pro Warm. The extra modes on the Zebralight were a big plus for me. The Zebralight and Nitecore seem to be about the same weight, while the Armytek is a bit more approximately 20 more grams for the light itself, but claims to be built more robust and excellent waterproofing. I listed the modes and some specs of these three lights below hopefully it can be helpful. Let me know if I got something wrong on here.
