While I do have a couple of DeWalt drills, I’ve been a member of the House of Ryobi for 20+ years. Ryobi was the first to really push the idea of “one battery fits all” ecosystem with their 18V ONE batteries.
My Wife bought me a tool set for Christmas one year and I have never looked back. 20 years later I’m still using those tools and Ryobi still supports them. A new Lithium battery battery still works in my old tools. The “pro tools” do not take that track.
