Having had just on KA in my life -- a horrid range -- and being now a Bosch user, I would say there is no comparison. I swore I'd never buy KA again. Everything I have from Bosch is flawless. This is just anecdotal evidence, of course. I hope some of the experts will chime in. I will say, though, that I am of the strongly held view that one should buy the appliance, not the brand. I have Elux ovens because they met my needs best and I'm very happy. I have an Elux fridge that is a total dawg and won't hold temp, so go figure. Good luck.

In general, it is never a good idea to stick with one brand for all appliances. Makers are good at some and bad at others. KA is notoriously bad at ovens, somewhere in the middle or better with dishwashers and perhaps refrigerators. We here issues with bottom of the line Bosch DWs and some of their laundry machines, but glowing reviews for cooktops and ovens.
