"By comparison" is an expression that we use to show how two or more things are similar or different. It is used to compare things, to point out differences or similarities so that you can understand them better. For example, you can say "This smartphone is expensive by comparison to others on the market" which means compared to other phones, it is more expensive. So, use "by comparison" when you want to emphasize differences or similarities between two or more things.
