We just went through that process. The wife did all sorts of online shopping/reviews then we went to Nebraska Furniture Mart to touch everything since we originally planned on Kitchen Aid, good stuff just didn't check our boxes. We went to Factory Direct to get more perspective on brands/items that NFM didn't have on the floor.
We had a couple details that pushed us to split brands and ordered Bosch for the fridge, OTR microwave and dishwasher, Viking for dual fuel range all in stainless. We wanted the same fridge configuration as you, with water and ice through the door, this deal with it inside the fridge kills the convenience of having it. We also wanted the best dishwasher value and as little electronic crap on the range as possible (yes, I know it is dual fuel and that is contradictory but it was part of keeping the Boss happy by not having a digital control panel). The OTR and range look good together despite being different brands.
