Milwaukee - highest price tool , built to last
Dewalt / Makita - again high priced and well built
Bosch - trades man / diy border line , well built
The rest imo are cheap imitations lol
I think not a single brand make all their tools as good.
Some brands are good at cordless 18v, some at corded, some at saws, and for shop stationary tools like delta, general, time savers, etc its even more true.
You can get all ADA about this and get all your tools from the same brand and get their jacket, gloves and hat.
The truth is that when you are freelancing and working with contracts and budgets, price and quality needs to be balanced.
If it was the case to buy the best of the most expensive then go get FESTOOL, I've used them all and their $500 drill made holes as well as my 18v RYOBI for 1/10 of the price and I let the other guys a the jobsite borrow it, unlike my friend with his unpopular FESTOOL. Geez, the $1200 festool plunge circular saw and it's rail we're awesome but I made a $10 jig with plywood for my makita.
