I have had a Bertazzoni range top for a couple of years and have absolutely no complaints... it’s fantastic. But, when I was shopping there were quite a few negative reviews about the oven, so I would definitely check and see if that’s still an issue. (I didn’t care, because I have separate ovens.)

My (admittedly not very researched) understanding is that Wolf isn’t really that great of a line, and my experience with Thermador ovens wasn’t super positive... I actually replaced them a year ago. Hopefully you get some more knowledgeable feedback in the appliances forum. :)
