Coming from electric, I can say that this definitely heats and cooks faster. I had thought that gas was supposed to hear more evenly, but I don't find this to be the case. Definitely a bit of a pain to clean vs a flat cook top, but once you've taken off the pan holders it's fairly smooth for wiping down. The griddle that came with it is really rough! Shredded the paper towel I was trying to use to spread the vegetable oil on to season it. 

On to the good things. Lights fast and reliably. Great materials for construction. Knobs are hefty, the racks above the burners are cat iron out something and they have little silicone feet on them to make it so they don't clang on the base. The knobs have little silicone gaskets on them so they quietly go back on after cleaning. Really ups the lux feel.
