I would go with Bosch over the brands you mentioned. KA would be my second choice.

I’ve been using a Samsung (not WiFi) purchased through Costco, for just about six weeks. I’m very happy so far with this range, it cooks well stovetop and oven, is easy to clean, has intuitive controls that are well placed, has an actual warming drawer, and it’s very attractive. The middle grill is not likely to be used much, nor is the wok attachment so I can’t comment on those. My other option was the Bosch and it really came down to which would look best in our kitchen and our confidence in Costco.

Will add that dual fuel wasn’t desired because I am not a baker, so not worth the money or electrical upgrade.

I wouldn't waste money on dual-fuel. From what I can tell, the overall quality of the range makes a much bigger difference. I have used both gas and electric ovens, and they both work just fine after you have adjusted to their own specific peculiarities. And honestly, that's true for all ovens. No two models are exactly alike.

I'd stay clear of the brands that you quoted. While they certainly sell a large volume of units, the horror stories here on Houzz across all their product lines are somewhat off-putting.

If you have been reading this forum for a while, you'll see that I am personally a huge fan of Bluestar ranges. You could maybe find a RCS series range, but it'll likely be just outside of your preferred price range. Make sure you buy a model with the open star shaped burners though. That's what sets Bluestar apart from the rest of the manufacturers.

Alternatively, consider induction. It has lots of good things going for it. It might be a better fit for your needs. And there certainly are models that fit your desired price range.
