Between only those two, I'd go with Milwaukee. Usually heavier duty parts. Personally, I'm partial to DeWalt. Out of 20+ DeWalt tools I own, there was only one I ever had a problem with (quick change on reciprocating saw)

I have had good experiences with both of them. Milwaukee had battery issues back in the day (maybe 10 years ago) but seem to have fixed that problem. I would pick based on price and which one actually feels more comfortable in your hand. If you work in construction or take the tools to places other than your home regularly, I would steer away from the combo kits unless you are saving enough money to buy cases and batteries for each individual tool. I have found it to be a pain in the wazoo to carry the whole combo kit into a job when you only need one of them. If you are strictly going to use these tools around your own home, you may want to consider buying all the same brand and voltage for the convenience of being able to use the same batteries with all the tools. Here is a list of the tools I have used and which brand I would pick accordingly. Cordless Drill: Makita Cordless Sawzall: Milwaukee (I have never used a Makita) Cordless Impact Driver: Makita Cordless Circular Saw: Makita Cordless Hammerdrill: Milwaukee Cordless Bandsaw: Milwaukee (I have never used a Makita) One other brand you may seriously want to consider is Panasonic. I have a cordless drill and metal cutting circular saw that I would not trade for any other brand of tool on the market. Greatest tools I ever used.

Either is excellent. Consider what cordless tools you're going to purchase, and see who has the best range of coverage over those items. Generally you get another battery with each tool you purchase, so for the sake of convenience you want all the batteries you purchase to be the same kind for the sake of interchangeability. I've owned Makita and DeWalt, and spent plenty of time using Milwaukee. The Makita is somewhat lighter duty but when not trying to drive 5/8 lag screws through railroad ties (which was just the one time), the extra muscle of the DeWalt just translates into extra weight. And the Makita did drive a few lags, too. The Wally just did it faster. I'd put Milwaukee on the same level as DeWalt for both toughness and weight. They're both stout jobsite tools. The Makita can be had nearly as tough, but there's a certain _something_ that I just can't put my finger on. But in my experience the Makita is lighter enough that I can feel it in my shoulders at the end of the day, in my toolbelt not being dragged quite so far down my butt as with the DeWalt or Milwaukee. Ultimately though, it's your money. You choose. I'd say either is a good purchase with few regrets.

last i checked, milwaukee had a longer warranty. milwaukee makes tools for everyone from the housewife who hangs pictures all the way up to the heavy industrial/commercial construction workers makita is mostly light duty stuff. just fine for around the house on occasion, but not the kind of thing you want to make your living with everyday. commercial and industrial pros use milwaukee, dewalt, hilti, and bosch. if its just for occasional hobby use, the makita is fine. if your have to depend on a drill on a regular basis, get the milwaukee.
