Main trade-off

What you give up
Recommendation switch
Choose KitchenAid Commercial Series 8-Quart Bowl-Lift. Commercial 8 supplies the larger bowl, subject to the recipe limits.
Choose KitchenAid 5.5-Quart Bowl-Lift Stand Mixer. KSM55 provides the half-speed setting in a smaller format.
Choose KitchenAid Commercial Series 8-Quart Bowl-Lift. The eight-quart model is the commercial-series option of the two.
Choose KitchenAid 5.5-Quart Bowl-Lift Stand Mixer. The smaller 5.5-quart bowl places less demand on cabinet space.
What matters in practice
Commercial 8 adds 2.5 quarts, about 45% nominal room. That is useful when a recurring batch is too large for 5.5 quarts, but also means more bowl to store and wash for ordinary recipes.
Check the exact commercial model, safety equipment and use requirements before purchase. A household bowl-lift layout by itself does not make the smaller mixer interchangeable with a commercial-series unit.
KSM55 includes half speed for folding delicate additions. Choose it for that ordinary kitchen routine when an eight-quart batch or commercial specification is not needed.
