The catch
KitchenAid 5.5-Quart Bowl-Lift Stand Mixer
Next to the Artisan tilt-head mixer, it weighs more and stands taller.
Side by side
KitchenAid KSM55 vs Pro 600: KSM55 makes flour easier to control, Pro 600 adds just half a quart
Quick verdict
For flour control and standard heavy batches, KSM55 is the cleaner fit. Pro 600 gives you an extra half-quart of room, and it is worth considering if you are comfortable with the exact seller and warranty.

What this page compares
A current bowl lift with a gentle start goes up against a larger legacy workhorse.
This one comes down to bowl and speeds first, then to the limits of your own setup.
Day to day
How each one fits your routine
Half speed is for folding and will not speed up a bread routine
If you regularly fold delicate ingredients into a mixture, KSM55's extra half-speed setting is a practical reason to choose it. It does not give you a new kneading speed, since KitchenAid's guidance specifies speed 2 for yeast dough. Pro 600 lacks the dedicated half-speed position, so decide based on whether folding is a recurring job, and do not treat eleven speeds as universally better than ten.
Where this comes from
Half speed is listed on the exact KSM55. In KitchenAid's bowl-lift guidance, half speed is for folding and speed 2 is for kneading yeast dough. Those instructions set two tasks apart and do not rank overall motor capability.
Half a quart does not translate directly into more bread
If you are choosing Pro 600 for a larger bread recipe, check the flour or dough allowance for that recipe in the model's instructions. The six-quart versus five-and-a-half-quart bowl labels do not carry over as the same ratio in kneading capacity. Pick Pro 600 only when its documented recipe allowance supports the job you have in mind. When both fit the recipe, KSM55's folding control can be the more useful difference.
Where this comes from
Each is a bowl-lift machine with a nominal bowl capacity. The specific recipe and operating instructions determine dough load, so the small difference in bowl volume is not turned into loaf counts or a dough-weight limit.
