Personally I prefer Makita battery tools for their quality and broad options of different tools working with same 18V batteries... but I had to go with DeWalt as they have better availability and service in my country.

DeWalt surprised me with the quality of their brushless tools and I decided am happier when they decided to release 60V tools... but maintaining the battery compatibility with their "old" 20V system.

BTW DeWalt 20V system doesn't look different from their competition in 18V... 20V is only the open circuit voltage when battery is just loaded... like their competition... but 60V is really a tech difference.

I recommend DeWalt 60/20V system.
