All three can express contrast, but they have different nuances. に対して is the most general and simply sets two things in contrast. 一方で is often used to show two different aspects of the same thing, or to introduce another topic. 反面 specifically highlights the flip side or negative aspect of something positive, or vice versa.

There is no single Japanese word that directly translates 'in contrast' in all contexts. Phrases like 対照的に (たいしょうてきに) exist but are more formal and literary. In everyday speech, using patterns like に対して or 一方で is more natural.
