Protomelas yellowchin Pombo Rocks vs Otopharynx sp. spots

[taeniopareius]

Wondering in term of male full coloration and color duration which one is more bright/intense between Protomelas sp. yellow chin Pombo Rocks/Reef and Otopharynx sp. spots Sani? Is Protomelas more blue with brighter yellow on lower mouth and belly? I have Otopharynx already and wondering is Protomelas more attractive or just about the same or not. Any suggestion?
