I'm a Makita guy, have too many tools to change now. I have several drills, drivers, 1/2" impact, vacuum, blower, chain saw and on and on. Quite happy with them all really.
In the 1980s I bought a Makita 9.6v drill. It wasn't great but wow was it handy. It had a metal case and room inside for an extra battery and some bits etc. Sadly it got stolen when our office was burglarized, insurance covered it. Then I got a Milwaukee 14 volt, circa 1997 (?). It had a nice box, two batteries. It was much more powerful and longer running compared to the old Makita. Eventually, the batteries became weak and weren't holding a charge.
Then I had a Dewalt 14.4, the last Dewalt Id ever buy. It was again new more powerful than the one before it, a crappy case but ok. Worked ok, all in all, felt cheap compared to the Milwaukee. I had some work to do at home so I had the drill charging in my basement on a workbench. Long story short I go out with my wife for several hours. We come home the house stinks to a level that cant be described. Its an acrid stick to you smell, burning awful odor. We start searching the house, almost ready to call the fire department. I look downstairs and find the Dewalt charger and battery smoking and half-melted. It was so hot it could not be touched, anything flammable in contact with it may have ignited. I unplug it and move it to the concrete floor to cool, even the wood bench where it sat was smoking hot. Now the good part! Bring it back to the store where I bought it, sorry not under warranty we can sell you a new one. A month later the big box store has a Dewalt dealer in the store. I tell him my tale, I get "oh yeah we had some trouble a while back, I can give you a ten percent discount on a new one". No thanks keep your junk and be grateful I'm not making it into a suppository, is what I was thinking. I was probably smoking more than the charger at that point, deep breath, deep breath, walk away...
I guess I did one better, bought a Makita 14.4 volt in all its glory. Years later made that one my house drill and work went on to the 18volt. The 14 volt still works nearly twenty years later, one original battery works, ish. I bought one new one great for around the house.
Around here, building trades use Dewalt (the rich guys use the big$ brands), mechanics use Makita and now Milwaukee, industrial use mostly Makita. All of it has crossover and lots of keeping up with the Joneses.
If I was starting out, I'd probably be looking closely at Milwaukee. If I was just using them at my home I'd seriously look at Ryobi or Ridgid. People that have them like them and speak highly of them.
