Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. The SMO's main job is to focus and project light from the source. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. The CU6 flashlight has multiple switch options. The electronic switches may have a higher chance of standby drain. Mechanical switches are usually robust. A simple press or click of the rear switch turns the flashlight on or off.
