I had a Makita for twenty years and had to replace one battery 14.5 volts. My Dewalt is a 12 volt, a good drill but, I don't like the chuck, it loosens, at the most inopportune times. The batteries are a year old and are on the charger constantly, they don't hold charges long.
My son-in-law, a Master Electrician has all of them and, a Bosch, very, very nice but, as expensive as a shiny new nickle.
It all depends what you want, the jobs you do, how much you use them.
I have a wood-working shop in my basement, I do model homes and bird-houses. Although I use them all the time, I'm not pressed. I can get by on a "almost good" without paying the high price.
