When it comes to discussing similarities and differences between two things, the phrase "in comparison with" is often used. However, for variety and clarity in writing, it is helpful to have synonyms for this phrase on hand. Some alternatives include "by contrast", "in contrast to", "when compared with", "as opposed to", "contrarily", "as a counterpoint", "on the other hand" and "whereas". Each of these phrases can be used to indicate a comparison or contrast between two or more things and can be substituted for "in comparison with" in order to add variety and complexity to your writing.
