We are looking at the entry level option. They have 15K BTU

The RNB is more expensive than the entry level model and we are in that range.

I have the same question as you, nid15. I wish someone could just answer the question as asked and not look at this/that/or the other. Did you decide on anything?

We ended up with the KitchenAid. You do loose out on the bragging rights of brand names but it is a badass range and we got a lot of compliments. We now feel the double stack burners are better than the open burner since the flame is more concentrated. Even now, we have to turn it down a bit if the vessel is not very large. also, the simmer function on these double stack burners is amazing. I can keep milk without boiling over. The oven works good but I wish it had a display. you can do a lot of things with the app. So far we are quite happy with the purchase.

Thanks for the feedback, nid15. I have a question. How is the flame more concentrated on the double stack burners than on the open burners of a BlueStar? Seems to me the flame is more concentrated on the BlueStar because it's all under the center of a pan. I also would like to know from someone about how 20 BTU open compares to a 20 BTU sealed. Still trying to decide. Also, the KitchenAid is out of stock until mid January, unfortunately.
