Milwaukee dewalt and Hercules at hf are all really good. We run all dewalt stuff at work and it is OK. I run milwaukee in my shop at home and it is awesome. M18 high torque and a 3/8 m12 stubby. I wouldn’t hesitate to buy either impact. I like milwaukee because of all the other tools in the same battery platform. In my opinion dewalt is much better for construction type work but milwaukee wins hands down when it comes to automotive and mechanical tools.
