We replaced a very old wall oven that finally broke down.  There is no comparison there.  In general, we've found this unit to be fairly quiet and easy to use.  The integration of the device with their web app and Google home is easy to setup and useful, e.g. the oven will send a message to your phone via their app that its done pre-heating or that a timer has ended.  I find this particularly useful when trying to deal with both the kids and making their food.
