I've used more cordless tools that most folks will ever see, no brag, just fact. Over the last 40 years I've used most all brands. They all work, some are stronger than others. You have to decide how much power you need. My ideas:
Highest power needs,,,Flex beats them all handily, porbably 5% of all users
Moderate power...Milwaukee, Makita, DeWalt, Rigid, porbably 10-15% of all users
Mid range power...Hercules, Ryobi, Bauer, probably the vast majority of users fit this category
Low power... almost anything out there will drill a hole or drive a small screw.
I'd like to jump on the boat about where these tools are made, but it just seems senseless. You can't touch anything from calculators to cars that is not partially made in China or the Asian rim countries. I can tell you that for many years I had a trove of Milwaukee 18v and 12v tools and never went thru a single battery and I have over a dozen or more. In fact, one of the guys who works for me has all of those tools and as far as I know all of the batteries, still no failures.
What do i use?
90% of the time Makita 12v brushless drill and impact driver
10% of the time, Bauer 18v drill and driver, yep, I had some batteries and just kept going and so far haven't looked back. If I had it to do over I'd have gotten Hercules, but no biggie.
If I need more, which I almost never do, I have a Flex 24v hammer drill and a corded Hilti. They hardly ever get used until we need to drill through brick.
I don't get hung up on brands, I get hung up on actual use and what works.
