I have a Dewalt cordless drill that I've used very little for the last 4 years after buying a Ryobi drill and driver set. They aren't the most powerful for sure but its really convenient to grab the bag with both plus their charger plus driver bits and drill bits.I think milwaukee is likely right there with dewalt some of the departments i used to work within had contracts with milwaukee and hilti,the milwaukee fuel was very popular.Many different options for both.
Using dewalt for so many years and seeing the abuse and reliablility has just kept me loyal.
The Dewalt has set so long now that the batteries seem weak even after charging.☹
