Why not just get the Sully range and not have to bother with a wall oven then just a MW not expensive and change it when it dies.

We have a Cluny 1400 and also a Miele conventional oven. I find myself using the Miele routinely unless I need a second oven, or if I need to heat an oven fast (the little gas oven in the LC is pretty quick). We're redoing the lake house kitchen with the same range, and this time have a Bosch single conventional wall oven (due to Miele backorder issue). Issues for me that justify the additional wall oven include size (the inevitable "25 lb Thanksgiving turkey" issue--or multiple half sheet pans, just easier to maneuver in/out of the Miele). Temp accuracy (I never truly calibrated the LC ovens and setting temps is a bit random vs the digital set on the Miele. Light bulb. None in my LC ovens.

I dislike combo MW/convection ovens as I believe MW's always die and then what do you do? Give me a separate cheap MW hidden in a garage door cabinet. Chose not to do a steam oven and got an Anova Precision Oven instead. It's an amazing combi oven that far outperforms most residential steam ovens (incredibly precise temp control, steam controllable 0%-100%, bagless sous vide, air fry capability, automatic oven control from recipes on app, etc) although I'd be the first to admit that the horrible connectivity issues make it a questionable purchase for anyone not willing to do a lot of troubleshooting.
