Quick answer
Consider microwave cookware if you already have a compatible microwave and want a rice-making setup that can be put away afterward. Consider an electric rice cooker if rice is a regular part of meals and features such as an appropriate minimum batch or a keep-warm mode would improve your routine.
Choose by the meals you actually make. A smaller-looking product is not automatically the better small-kitchen purchase if it occupies the microwave when you need that appliance for the rest of dinner.
Write down your usual batch
Start with the amount of dry rice you cook, the type of rice and how many separate cooking sessions you need. Then check each product's instructions for that batch. A vessel's total volume is not its safe uncooked-rice capacity, and “cups” can refer to different measurements or stages of cooking.
For the NS-LGC05, Zojirushi lists a range of 0.5 to three supplied measuring cups for short- or medium-grain white rice and long-grain white rice; short- or medium-grain brown rice has a lower maximum of two cups. Use the supplied rice cup, the matching water-level line and the appropriate menu setting. These are uncooked-rice capacities, not the pot's total volume. Other grains and models need their own capacity checks.
Check appliance compatibility before cupboard space
Joseph Joseph describes the M-Cuisine set as a two-liter cooking pot with a colander, measuring cup and multipurpose paddle. Its current care guidance specifies microwave ovens up to 900 watts. Do not improvise a higher-wattage setting. Use microwave mode only, never convection mode, a conventional oven, a stovetop or a grill.
For this set, rinse the rice in the colander, place it inside the pot and add the water specified for your rice and batch. Fit the lid and secure it with the paddle without covering the vent holes. Use the supplied cooking chart, check that the grains do not dry out during cooking, and protect your hands when removing the hot pot. Joseph Joseph specifies a five-minute standing period after cooking before fluffing and serving.
For microwave cookware, measure the assembled vessel against the available space and consider safe access for removing hot food. For an electric cooker, plan space for the appliance, cord, opening lid and the clearance its instructions require. Include the cupboard where it will live between uses, if you do not intend to leave it out.
Think through the whole meal
A microwave rice routine uses an appliance you may already own. The practical question is whether that appliance is available when the rice needs to cook. Sketch a normal dinner: rice, vegetables, sauce and reheating. If those steps compete for the microwave, an additional cooker could earn its footprint. If they do not, another electrical appliance may add little.
An electric model's keep-warm setting can help when people eat at different times, but its limits depend on the model and food. For the NS-LGC05 example, Zojirushi allows up to 12 hours for the rice menus it marks as suitable for keep-warm. Do not use that mode for mixed rice with added ingredients or steel-cut oatmeal, or to reheat cold rice. Do not add more rice to a batch already being held warm. Do not assume an automatic switch to keep-warm makes every menu suitable for holding. Check the equivalent limits for any other cooker.
Compare cleanup, not just cooking controls
List the pieces you would wash: cooking vessel, lid, basket, utensils and any removable components. Then check each manufacturer's care directions. Dishwasher compatibility applies to specified pieces, not an entire electric appliance.
For the M-Cuisine, the rinsing basket may replace a separate strainer, but it remains a part to clean and store. Joseph Joseph lists the set as dishwasher safe and warns that strong colorants such as turmeric can stain it. Dishwasher compatibility is a care specification, not evidence that this set takes less time to clean than another cooker.
Choose the simplest option that fixes a real problem
Keep your existing method if it reliably makes the batch you need. Choose microwave cookware when appliance fit and meal timing work in its favor. Investigate an electric cooker when repeat rice cooking, supported batch sizes or specified warming features justify another appliance.
