I own a Sawstop. The saw is amazing, the dust collection is as good as advertised, plenty of power, and all of the benefits of a cabinet saw. I have never used a Powermatic, so I can't compare it to that manufacturer, but I would assume it is on par with that saw in every regard. The brake is a bonus, but without it I would buy this saw again. Try and get to a store where you can compare the two side by side if you can, or perhaps maybe someone you know has one where you can see it up close to help you decide. Maybe post a thread for Sawstop owners and see if there is anything they dislike about their saws. Most people have strong opinions about Sawstop, but I haven't seen much negative about them from owners. Call customer service for each company, I did, and was more impressed with Sawstop before and after I bought one. Have fun with your decision and best of luck!
