Currently I have a Ryobi and a Bosch. They both work well but the first Ryobi had switch problems several times until I finally gave up and tossed it. The Bosch - way more powerful so it gets the bulk of my work while the Ryobi gets stuck with the rotary wire brush - which brings up a hijack. Is there a rotary wire brush, straight wires, that will continue to operate more then 2-3 light to medium uses without shedding its wires, usually stuck in my forehead or shirt. I've tried several brands, with the DeWalt being the worst with a couple of foreign being better.
