About this comparison
Choose between a current gentle-start bowl lift and a larger legacy workhorse.
The practical choice turns on bowl and speeds, then on the constraints in your own setup.
Before you choose
How they fit your plans
Half speed serves folding rather than a faster bread routine
KSM55's extra half-speed setting is a practical reason to choose it when you regularly fold delicate ingredients into a mixture. It is not an invitation to choose a new kneading speed. KitchenAid's guidance specifies speed 2 for yeast dough. Pro 600 lacks the dedicated half-speed position, so choose around whether folding is a recurring job rather than treating eleven speeds as universally better than ten.
Facts behind this advice
The exact KSM55 lists half speed. KitchenAid's bowl-lift guidance assigns half speed to folding and speed 2 to yeast-dough kneading. Those instructions separate two tasks rather than ranking overall motor capability.
Half a quart cannot be converted directly into more bread
A person choosing Pro 600 for a larger bread recipe should check that recipe's flour or dough allowance in the model's instructions. The six-quart versus five-and-a-half-quart bowl labels do not establish the same ratio in kneading capacity. Choose Pro 600 only when its documented recipe allowance supports the intended job. If both fit the recipe, KSM55's folding control can be the more useful distinction.
Facts behind this advice
Both are bowl-lift machines with nominal bowl capacities. Dough load depends on the specific recipe and operating instructions, so the small bowl-volume difference is not converted into loaf counts or a dough-weight limit.
