A:Answer Hello mb - this is Nancy at GE Appliances and I am happy to help you. Both of these ranges are very nice models and both have three small and two large burners. The PB911SJSS also offers the edge-to-edge cooktop, which is a large, seamless surface that is easy to wipe away messes. It also offers the True European Convection with Precise Air, "Warm" mode feature, an additional heavy-duty oven rack, full-wrapped stainless oven door, You will notice that the backsplash is also different. I hope this helps! Thanks for checking with us !
