A useful comparison answers a real question. Imagine a friend choosing between two evening classes. Begin with the decision: "The main difference is the schedule. Class A meets twice a week; Class B meets only on Saturday." The listener immediately knows why the information matters.
Select two or three criteria, such as timing, travel, and opportunities to speak. Avoid inventing details merely to fill a comparison table. If the cost is unknown, say, "I have not checked the fees yet."
Explain a conditional preference
Try this recommendation: "Class A gives you shorter sessions during the week. Class B is easier if you work late, but the Saturday session is longer. I would choose A if your evenings are usually free." The preference follows from a stated need.
Notice that "better" needs context. "A is better for regular weekday practice" communicates more than "A is much better." Likewise, "less convenient for me" describes your circumstances without pretending to be a universal judgment.
Switch roles and ask your partner to change one requirement: "Actually, I travel on Saturdays." Revise your recommendation rather than repeating the original answer. Review whether you used comparable facts for both choices and whether the final suggestion matches the listener's priorities. This develops explanation skills as well as comparative forms.
