Which is better, Omega seahorse or constellation?

Hello, constellation series is the most famous series of Omega, and hippocampus is the oldest series of Omega. The 35.5 dial of Constellation Series is Omega 2500 movement, and the 38.5 dial is 8500 movement. The hippocampus series is basically 8500 movements except 007. If you pay attention to style, the constellation is better and the hippocampus has the best cost performance.
