I have a Whirlpool oven, I like it, not sure if it's the best or not. I also have a Whirlpool drop in gas stove which I love. My stove is gas, the oven is electric, two separate appliances.
No one allows me close enough to an oven to check mine. I LOVE FIYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA and hate cooking lol
We've had good luck with Jenn-Air for the last 20 years. Expensive but they were more than adequately responsive when I had a problem with the new stove that we just bought a year ago. It was made in America too.
