User Preferences: Consider who will be using the appliance and their comfort level with technology. Some users might prefer the simplicity and tactile feedback of rotary knobs, while others might appreciate the advanced features and modern look of touch displays.
Kitchen Environment: In busy kitchens where ease of use and durability are critical, rotary knobs might be preferable. In a more controlled environment, or where a modern aesthetic is desired, touch displays might be a better fit.
Functionality Needs: If advanced functionality, programmability, and smart features are important, touch displays offer significant advantages. For basic, reliable operation, rotary knobs are often sufficient.
Ultimately, the choice between rotary knobs and touch displays will depend on the specific needs and preferences of the user, as well as the intended use and environment of the appliance.
