Organize the same features for both options before comparing. A difference in one feature does not establish that one option is best in every way. Do not invent a preference unless a goal is given.
Worked example
A light folder holds less, while a heavy folder holds more. Which is preferable depends on whether carrying weight or capacity matters most.
Original fiction: Two Display Stands
The class tests two fictional display stands. Stand A folds flat and holds three posters. Stand B cannot fold, but holds five posters. Both fit through the classroom door and both stay upright in the classroom test. The group needs to carry a stand on the bus for an event with only two posters. No outdoor wind test has been done.
