I have a Ryobi set at home, although we use Makitas in robotics and the woodshop. I have 2 regular drills and an impact drill.
I personally like the Ryobi better because it's a little faster to swap out batteries, the batteries are larger, it makes a really satisfying snapping noise when you put new batteries in. However, functionality wise both the Makitas and Ryobi are good.
