Each has its advantages and disadvantages. I've blown two or three mag bulbs in ten or so years and have had a dozen or more LED lights break or fall apart. the LED lights are small and run more efficient for sure but just don't put out a whole lot of light unless you get into the really high end. My ARC AAA will let you see a couple feet in front of you but a AA or AAA minimag will let you see quite a way farther into the woods. I carry one of each and the bulbs in the AAA minimag can be put into the Arc AAA if needed. Its kind of like asking is a fixed or folder better or which caliber is better, depends on the intended use.
