I really had no brand loyalty beyond my Dewalt 12v tools, which I still go to first and foremost. And I have an ancient Makita 18v drill/driver (BDF542), which is still in mint condition, including the (3) 1.5AH batteries. In retirement I have some pending projects that have more demanding requirements and researched all the options. As I'm in the U.S., I had the good fortune of choosing between several 18-40V(+) options. I ended up going with the Hercules brand of 20v Brushless tools from Harbor Freight. I was primarily in the market for a decent hammer drill/driver and impact driver. For $225 USD I purchased that set with (2) 5.0AH batteries, charger, 5 year warranty on the tools, and 3 year warranty on the batteries. Tough to beat the value, and these Hercules tools have been reviewed and tested against the best professional grade offerings from the big names and have proven their performance. I have run them both, and they have exceeded my expectations. I've recently added the Hercules 20V/AC Jobsite fan ($30) and Brushless 20v angle grinder and an accompanying 8.0AH Extreme Performance battery (Samsung 21700 cells, BTW) for $99 bucks. The fan is a steal for that price and works great. Ditto for the angle grinder.
I take care of my tools. They're blown out (as needed), cleaned and stored in TSTAK or Bauer cases with self customized foam inserts. They will outlast me.
