I have the w5132 and the only difference I can notice between the 3.0 and 5.0 is longer runtime on the 5.0. If there's a difference at all in power it's not much.
Every since I got a Milwaukee 2763 6 months ago, i haven't used my snap on mg725 once. I like them both but my vote goes to the 2763. It stays in my cart and the mg725 stays in my box, no point in dragging air lines around for no reason
I have the 3/8th version. Same size body as the half inch one I think. Don't have a Milwaukee to compare it to but here's it compared to my snap on ct8810ag if that helps.
