But Ryobi and Milwaukee are both owned and manufactured by the same company TTI, they’re practically the same tools just with a different plastic shell
Owned by same company does not mean same tool. I own a bunch of m12 fuel and some Ryobi too. My Milwaukee stuff kicks the pants off of Ryobi but it is also a lot more expensive.
The AEG sub compact cut off tool, for example, is also sold as an M12 tool, and under the Ryobi name. Most of the AEG sub compact stuff shows up elsewhere in the TTI range, if you know where to look.
My battery drill, for example, had identical specs to a Milwaukee drill.
