Blenders Stand Mixers

They do genuinely different jobs -- a blender purees and liquefies (smoothies, soups, sauces), while a stand mixer's whisk/paddle/dough hook attachments knead dough and whip air into batters and egg whites in ways a blender's spinning blade physically can't replicate. If you bake regularly, a stand mixer isn't a luxury; if you mostly make smoothies and soups, a blender covers that and a stand mixer would be underused.

Higher-end blenders like Vitamix generally have stronger, longer-lasting motors built for daily heavy use (crushing ice, whole fruit with skins/seeds, nuts) without straining, plus tighter manufacturing tolerances that reduce vibration and leaking over years of use. For occasional smoothies with soft fruit, a budget blender's motor is plenty; for daily use with tough ingredients, the more powerful motor shows its value faster.

Not directly -- peak wattage (often the number on the box) measures the motor's brief maximum draw, not sustained cutting power, and blade design/container shape affect how well ingredients actually get pulled into the blades. A well-designed lower-wattage blender can outperform a higher-wattage one with a poor vortex; wattage is a rough proxy, not the whole story.

A 4.5-5 quart bowl (the common 'tilt-head' size) comfortably handles a double batch of cookies or a standard loaf of bread for most home bakers. Larger bowl-lift mixers (6+ quarts) matter mainly if you regularly bake in bulk -- multiple loaves, large batches for a group -- rather than everyday single-batch baking.

For single smoothies or shakes blended directly in a to-go cup, yes, and they're more convenient to clean and store. They fall short for larger batches, soups that need a bigger volume, or crushing a full bag of ice at once -- the smaller motor and container just aren't built for that scale.
