I have a 36" Gagg induction cooktop. I love it, but not that much when I look at the price in isolation (it looks so inexpensive blended into all the other reno costs.) I would not hesitate to get Thermador or Bosch instead.

Best product of the money is Bosch- hands down. Flex induction. Reliable. Affordable. Very few if any complaints about Bosch induction here.

I looked at Gagg, but at the time (3 year’s ago) I didn’t think it had as much to offer functionally as the Bosch. I do have the Gagg ovens, though. I ended up buying the Miele in the end because it has a more intuitive interface which is what I needed for my DH’s infrequent cooktop usage!

You mentioned being a real foodie - the benefit of the Gaggenau is that you can use the entire surface for cooking. The difference in cost between the Gaggenau and the runner-up would be about $50 per month for the next four years. We have a client who is doing all Miele with the exception of the cooktop, and they're going with the Gaggenau for the ability to use the entire surface. Best of luck with the new cooktop! - rf

These are really not Apples to Apples comparisons

The Gaggenau CX491610 is a full surface Induction cooktop

The Thermador CIT365TB is a 5 pan Induction cooktop

The Thermador CET366 is a radiant electric cooktop (not Induction)

You may want to consider the Thermador all induction CIT36XKBB or their Zone induction CIT367TM
