Im on Makita cordless gear atm. Past has been, Panasonic, Bosch, Hitachi, Hilti. I always have drill/driver with hammer, impact driver, reciprocating saw, grinder as a minimum. Most of the little 1/2" impact wrenches are based on their (brand) impact driver. So youll only find the lower end of the torque busting spectrum. Go to your big tool brand outlet and if you have a good repore with a sales member, ask them the % of return of each brand (they have these numbers) also ask them who is the easiest to deal with re warranty (they definitely know this)
From my understanding Milwaukee has a higher % or return than Dewalt but have been easier/better to deal with regarding warranty... but a shift seems to be in the air re that ease...
Im happy with my makita, no problems since purchase a few years ago and I use my cordless kit every single day. Mostly impact driver, drill, planer, grinder, radio and blower. I have one of their bigger 1/2" impact wrenchs...1000nm I think it is. I sometimes do structural steel and the stock small one is not enough for M16 and M20 structural bolts
I did keep my Hilit rotary hammer drill and collated screw gun/driver in 22v cordless as these are best on market AFAIC
