I couldn't tell you which is the best functioning, since I have no experience w/ the Miele. But for the time that we've had the Bosch Benchmark unit installed (variously since last November -- the kitchen reno is still going on), no complaints from us. There were a couple of times when the bridge burner suddenly just turned off. While I'm 99% sure I didn't accidentally hit the Off button, I can't say positively. I'm taking a wait and see approach. One of the selling points of the Bosch (for us) is the large burner's positioning towards the rear of the cooktop (closest to the downdraft vent hood). I'll use that large burner a lot for sauteeing, and it'll help for it to be right next to the exhaust. Good luck with your choices!
