Best means different things to different people so you have to understand your needs, wants, priorities, and options to make the best decision.
While the quality and beauty of McGizmo lights is indisputable, they are not the best choice for everyone. In my case I don't own any McGizmos and probably won't for a number of reasons. First, I generally prefer aluminum over titanium as it's lighter and offers better heat transfer. Titanium is generally tougher but so hard to machine I'm unhappy with the quality of finish on most Ti lights I've tried. Second I prefer more brightness settings and a higher maximum brightness than McGizmo lights offer. Third I prefer a User interface that allows instant access to both the highest and lowest output settings. So for me McGizmos don't work. They are terrific lights and seem well loved but you just have to understand your needs and priorities. If they match a McGizme that's a great choice.
