な-adjective takes な before 反面, contrasting convenience with expense
• The two contrasting facts usually describe the SAME subject. • な-adjectives take な; nouns take である before 反面. • Register: neutral to slightly formal; common in essays.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~反面 is tested against.
一方で can contrast two different subjects or simply add a parallel point; 反面 specifically contrasts two opposite aspects of the same thing.
のに expresses surprise/complaint about an unexpected contrast; 反面 is a neutral 'two-sided' statement without emotion.
