Not a dad, but definitely team DeWalt.

For those who hate being stuck with one brand because the batteries are so expensive you can buy adapters to convert between them. For instance I use a rigid battery with a ryobi tool etc and it works great! I've seen adapters for working between most of the brands since almost all the tools are 18V. I've seen ones that jump between lower voltages and higher ones which is a bit sketchier but are likely fine as well. https://www.google.com/search?q=power+tool+battery+adapter

I got three of the four, just one more power tool set and I'll be sweet lol

Ryobi is garbo.

How about dads who went with the discount hardware store's brand. It's easily 1/4 Dewalt prices and comes with a 5 year no questions asked warranty? I spent like 80euros on two 18V cordless drills. I keep the receipt in the case they came in, and in the last 8 years I've abused the shit out of them, and have had at least one replacement. Just like Dewalt, makita, milwaukee, and ryobi, I have several batteries and charges, and a plethora of tools with the same battery.

I went to the store with a beat up drill, and the pimply faced teen at the register was like wtf?!? But the manager didn't want the full story on the phone. Only three questions "is it [store brand]?" "is the receipt less than 5 years old?" and "what are you calling me for then?". New drill, new case and new receipt. Oldest drill is about 4.5 years old now, so I guess that I have to torture the hell out of it and get a new one with 5 more years.

Ryobi is great for starting out. They're definitely not the best tools, but they're cheap. If you wear out something from them, you've earned the right to buy a good brand of that tool.

There used to be a great fifth house of Craftsman...

And let's not even talk about Snap-on, Northern, or AmazonBasics

My brother and I used Ego for lawn work. I'm not sure if these brands have lawn/garden stuff (I think I remember Ryobi does), but it's the same concept. I love battery powered tools, but I hate how the brands tie you in.

What about the tribes out in the wild? The Festools, Mafells and Hiltis?

No love for Porter-Cable?

Boooooo.

How dare they ignore the fifth and oldest house, House Craftsman

As a plumber milwaukee is where it's at, only brand that has a cordless snake/augur, air snake, compact propress, expansion pex and copper cutter tools.
