could not resist jumping in here, I am taking a break from electrical for a while ( waiting for knee surgery and industrial work again) and spend my days flogging tools and the main brands are Dewalt, Milwaukee and makita we send thrue the doors for cordless.
As others have said for automotive electrical and plumbing cant beat Milwaukee , there ratchets, impacts and drills to name a few cant be beat, and there M18 lineup of impacts is also impressive for power.
Dewalt nothing out there beats there 60v circ saw , as a die hard team red guy that hurts to say, but getting to talk to the reps, play with the toys back to back and basically act like a kid in a candy store yup , my money is the 60v circ saw.
Makita good all around brand, lacks power but makes up for it with finesse, around here its the finish carpenters and fine detail guys that use Makita. all in all , i am personally not impressed with them, there impact drivers are weaker then the others for shear torque however i can slow that sucker down and count the rev's where say Milwaukee its all go or stopped dead.
the end of the day it is tough to go wrong with any of them, but in a perfect world you will have a bit of all of them.
the biggest one, Price... cant beat DeWalt for the price, if your broke or just starting out i can get you a hell of alot more in Dewalt then any of the other brands out there for the same cash.
Ok stop reading now if you could care less about the main things I have found working in a tool shop.
Dewalt usually lower priced and higher margins as you can imagine the boss's like us to sell DeWalt. best support from the company reps also comes from Dewalt, and a close second goes to Makita. Milwaukee could not give a rats ***, unless your Home Depot good luck getting quick service or support from the reps. main reason we can figure on that, Milwaukee has the contracts to build the Ryobi and rigid line of tools as well. so the buying power from HD makes them there prefered distributor.
Makita recently launched there new massively upgraded line of tools giving Milwaukee and DeWalt a run for there money in the pure power department however its a new 40 volt platform with ZERO backwards support to there current 18 volt setup, yup thats right they flipped off there loyal customers again, and the price is just insane, do I buy 1 new drill, 1 new battery and charger ( as a kit ) or do i save a hundred bucks, and buy the Milwaukee (or 18volt Makita )Drill , impact , 2 batteries and charger) and for DeWalt 150 bucks saved.
and dont let the voltage of DeWalt's 20 volt line fool ya, read the fine print or look at the EU where they have tougher laws on advertising, its 20 volt MAX... they use the fresh off the charger floating voltage to get the 20 volt... in reality and in the EU its still 18 volts... atleast the new 60 volt batteries are backwards compatable to work in the 20 volt gear. and there newest line of the tools the FlexVolt Advantage systems that are 20 volt based but can make use of the higher voltages from the 60 volt batteries and gain a 30-50% increase in torque ( according to the reps that fill us in on the newest changes)
anyway thanks for sticking in there with me. Again honestly cant go wrong with any of them, see who sells what in the area and try to find someplace other then HD to buy them as they seem to sucker in the average house guy and charge a premium price to the uninformed , I know here the exact same kit from HD is usually 50-90 bucks more then what we charge, and our two other friendly competitors. once in a while thou.. Milwaukee and sometimes ( but rarely ) DeWalt will use them to liquidate older models of tools and blast them out at retail prices below our costs. and we dont buy 2 or 3 kits at a time... usually our orders from each of the brands are 3-4 million $$ at a time... which gives us really good buying power.
