So many brands, Wolf, Capital, Viking, Thermador and JennAir. A professional range originated in the restaurant. It features high output burners, but unlike the commercial the pro can abut combustible surfaces like wood. It also will not scald your hands like a commercial range....
But how do you pick a 48"?
1. Burner ratings...Vary especially on the simmer
2. Second oven can be self-cleaning convection, but most are non self-cleaning
3. Price...big difference
4. Clock and timer
