The rule of thumb with these simple comparisons in English is:
object of comparison + adj. (comparative adjective, or more + adj.) + than + other object of comparison.
Strawberries taste better than bananas.
Physics is more interesting than Physical Education.
Okay, so it looks a little complicated, but it’s not once you get the hang of it.
The easiest way forward is to memorize a comparative sentence you feel comfortable with, then simply replace its adjective with others that you want to use.
