I love our KA counter depth french door. Not familiar with Monogram-too pricey for us.

Have you search this website? Each of those has been written about a numerous occasions

GE Monogram makes a nice wall oven, but keep in mind that those are dressed up GE Profile and Café ones. If you can deal with the styling difference save the money and go with one of them. Thermador/Bosch also make good units

Thermador makes an excellent induction top. Bosch/Thermador/Gaggenau are the same company and share componentry made by BSH (one of the few companies that can claim this). Be aware that the freedom induction model is really nice, but less reliable than a standard 4 or 5 burner model.

KA makes a solid French door. So does Electrolux. The others out there are ok. I like GE as a company...but I have had more issues with their FD boxes than others. LG is good IF you have service and support behind them...if you don't or are in a rural area then don't buy them.

My advice - MIX AND MATCH. No brand makes the best of everything. Just doesn't exist. Find what fits your needs and budget in each category and figure out how to integrate them...not the other way around.
