I have both Makita & Dewalt and each has pros and cons but dollar for dollar Dewalt is hard to beat. The thing I like best about Dewalt is the 18v platform has been around for years and pretty much everyone carries batteries & stuff for them. Other brands can be a little harder to find decent deals on replacement batteries.
I use my tools hard and in 15+ years of using 18v Dewalt I have only had 2 of my couple dozen tools fail. One was our 18v shop vac the motor went when it was about 4 years old. I took it to a local service center and the guy behind the counter gave me a new one no questions asked. Not bad for something with a one year guarantee! I also had a switch fail on a sawzall and couldn't get that fixed because they changed styles and old switch was no longer available on a 12 or 13 year old tool. Not a bad track record!
My favorite Dewalt tool is my 18v shop vac. I would bet I use that 3 or 4 times a day 7 days a week. I use it for vacuuming out cabinets, cleaning up work areas when using drill, sawzall, etc, spot cleaning shop & office, etc. There is nothing nicer than grabbing a little cordless shop vac for a quick clean up when a job is done! To be honest I use it so much I actually bought a second one just to carry in my truck. Great for camping also!
I would pay the extra for the hammer drill as stated above! When you need replacement batteries typically around Christmas time Lowes or Home Depot puts two packs on sale for about the same price as a single battery most years.
