We've got DeWalt stuff here at work, I've got Ridgid stuff at home. Both sets seem to work for what they need to do. Batteries last long enough to do most any job. Depending on how much you're working the tools they last multiple days in the garage. Many people swear by Milwaukee and I've used them before and can say they're definitely the top dog for impacts in my opinion. If you're starting from scratch, I would buy as much as you can budget, but look into what other tools they offer to build a full kit in the future. I started with a drill and 1/4" impact driver, and since then bought 1/2" impact, reciprocating saw, angle grinder and jobsite radio. They also offer a hybrid fan that runs on battery or 110 volt. Which is nice for taking on a job where stinging a cord would be annoying.
