Both models deliver Sharp’s signature even cooking thanks to microwave drawer technology, which circulates heat evenly across dishes. However, the KB6524PSY’s higher wattage (1000W) translates to faster cook times, particularly beneficial when preparing dense foods like casseroles or meats. The SMD2440JS’s 950W output is still strong but may require slightly longer cook times for larger or denser meals. Users consistently note that the KB6524PSY produces slightly crisper textures when using auto cook programs, especially for reheating and defrosting.
In terms of footprint, both units share the same width (23.5") and depth (22"), making either suitable for standard cabinetry. The KB6524PSY’s slightly larger interior, however, offers more flexibility for bulk cooking.
The KB6524PSY edges ahead in energy efficiency, partly due to its higher wattage combined with optimized power management. It consumes slightly less energy per cooking cycle compared to its size and output. The SMD2440JS remains efficient but may require longer cook times for dense dishes, marginally increasing overall energy use.
Ease of use is a strength for both models. The KB6524PSY’s all-touchscreen interface is intuitive, with clearly labeled menus and a visual display that simplifies navigation. The SMD2440JS’s touchscreen + dial combination can be quicker for those who prefer tactile adjustments but may involve a learning curve for users accustomed to pure touch interfaces. Both models include auto cook and defrost presets that minimize manual input and reduce guesswork in meal preparation.


Both the Sharp KB6524PSY and SMD2440JS deliver excellent performance, high-quality construction, and user-friendly design. The KB6524PSY, however, stands out for its larger capacity, higher power, more extensive menu options, and slightly better energy efficiency. The SMD2440JS is an excellent choice for those prioritizing compact design and straightforward functionality without compromising on quality.
The Sharp KB6524PSY generally offers a larger oven cavity, typically around 24 liters, compared to the SMD2440JS, which usually has a slightly smaller capacity of around 22 liters. This difference can affect the volume of food you can cook at one time and may influence which model is more suitable for larger households or those who frequently prepare bigger meals.
Both models feature multiple cooking modes, including microwave, convection, and combination cooking. However, the KB6524PSY often provides a higher wattage for microwave power, which can result in faster cooking times, while the SMD2440JS may offer more preset automatic cooking programs for convenience. The difference in power and presets may influence cooking efficiency and ease of use.
The Sharp KB6524PSY typically has a more modern, stainless steel aesthetic with a flush fit suitable for under-counter or drawer-style installation. The SMD2440JS is also designed as a microwave drawer but may have slightly different dimensions and trim requirements. Accurate measurements and compatibility with existing cabinetry are essential when choosing between these models.
Both ovens include standard safety features like automatic shut-off, child lock functions, and overheat protection. The KB6524PSY may include additional convenience features such as sensor cooking for automatic adjustment of time and power, while the SMD2440JS focuses on intuitive controls with easy-to-read displays and programmable presets. Users may prefer one over the other depending on the balance between automation and manual control.
Typically, the KB6524PSY is positioned as a higher-end model, which may result in a higher retail price compared to the SMD2440JS. Both models usually come with a standard manufacturer warranty of one year, with options to extend coverage. Price differences can reflect additional features, materials, and performance capabilities.
