My suggestion is not to buy a set of any one brand. Decide which features you want in each kind of appliance, and then buy the best you can afford with the features you want, regardless of brand. Not every brand does every kind of appliance well. For example, I would buy a KA fridge, but not a GE.

Also, unless you really must do an over-the-range MW, I encourage you to get a real hood and have a separate MW elsewhere. OTR MWs, in my experience, don't suck up steam and smells well at all. I can't believe the difference when I use a real hood. It was important to us in our new kitchen to get the MW somewhere other than in the face of the cook and to get a hood that could actually capture and exhaust effluent.
