we have the JA 72" sxs, yes, they are the same fridge guts...I think the shelving is slightly different on the JA and maybe the door/handles? Not sure exactly. but both of these are also the same as the 72" Viking...except Viking raises the price $1000 and puts their own doors on it....

So, if you like the styling of the KA I'd go with that. We did the JA deal and I wanted all to match (handles). So we went JA..I liked the pro handle.

good luck!
