Milwaukee has been the top tool company for few years now. As an all rounder
I use Makita since they were the top when I started collecting tools. It will cost a considerable amount to convert.
They are 2nd best its very close and more than adequate performance wise.
The others like dewalt and Bosch are OK.
Ryobi is for peasants
Hilti and Festool if you are working with furniture and want to be very precise. But they have a hefty price tag
I'm a fan of Makita too, guess cos my dad always had it since I was a kid.
My fiance's dad is a Bosch guy.
Bosch and Makita are like 2 clans in these areas as they're similar in price and both quite good quality (German made Bosch).
When I do shit with my fiancees dad we both hope other guys tools will die so we can laugh how other one's would never have something like that happening.
