A resource I found useful when I wanted an impact wrench was a breakdown of which manufacturers are behind the different brands[1]. I knew not to waste time comparing a Black&Decker to a Porter-Cable since they're most likely the same thing. I also weighed the reputation of the manufacturer by averaging reviews from multiple brands. Getting lost in the illusion of choice is part of what makes online shopping problematic.
