I have no experience with other brands but Fenix is trusted and proven and as such, you cant go wrong. Solid and well built quality. Versatile for any lighting needs by having 5 brightness levels and an adjustable beam focus (wide/narrow). Before my purchase I really had no idea how bright 900 lumens was. Simply put, this unit's Turbo Mode (900 lumens) is more than one could ever need. Amazingly bright. I am a building inspector and this light provides enough brightness for any of my needs. For extended battery life using low and med is perfect for wandering around various property types. Having two more modes that are even brighter ensures I will never be wanting for more light. The eco mode will provide extreme battery life at a lighting level that is just right for reading in a dark place (for my eyes anyways). The AA battery source is another plus as it doesn't depend on proprietary batteries and AA sizes are available just about anywhere in a pinch. When entering creepy dark basements, crawl spaces, out- buildings, etc. The strobe mode scatters racoons, squirrels and other rodents quite effectively. Only improvement I can think of would be for a slight bevel or bump in the shell so you can set it down and have it stay in place as this unit will roll on a smooth surface (that has a tilt). However, placing the wrist strap as needed if you need to set the unit down works just fine.
