Meh, it varies from tool to tool. I've had a pair of Makita 18v cordless drills (one is an impact driver) for 11 years and they have been used and abused daily with no issues so far. I had a Makita sawzall for a while and found it to be weak and chintzy so I sold it for cheap to a buddy and started using a Hitachi beast that I got for free from a local window and door manufacturer.
Dewalt circular saw, although I still have my 30 year old Milwaukee for demo and dry cutting stone, granite, tile etc
Makita jigsaw
Bosch hammer drill
Rigid 10" cast iron top shop table saw
Bosch portable 10" table saw
Bostich framing gun and brad nailer
Dewalt compressor
Senco finish nailer and framing gun
Hitachi brad nailer and separate pin nailer
Dewalt brad nailer
Dewalt orbital sanders that I'm not a fan of.
Milwaukee corded drills (1/2" and 3/8" chuck)
Lg porter Cable router
Small Rigid trim router
Rigid sliding 10" compound miter saw
Makita 8 1/2 sliding compound saw
Hahahaha, and the list goes on.
The point is that I think you'll find that most tradesmen and craftsmen aren't married to one brand across the tool spectrum. I had a Rigid 10"

portable table saw that served me well for a dozen years or more and then I was helping my buddy with a project and worked with the Bosch and liked it so much I sold mine to a friend and bought the Bosch.
