If you ever go with a professional model, very carefully check the reviews and forums.
Many pro models are complete crap.
Many are not standard widths and or depths and some kitchen re-fitting.
Most of not all, can require pro level utility hook ups as well. Larger diameter piping, multiple circuit heavy AWG wiring (10 AWG and up!).
Another important consideration when installing a pro level stove/oven is sizing the hood correctly. This sizing requires taking into account getting enough flow, external venting, and having the right physical overhead dimensions.
We looked into going with a pro setup when we built the house but it increased the cost by somewhere around $15+ K. Too expensive for us.
BTW most of the cost is the actual stove an hood unit(s).
