I'd say Chitose is above Tachibana.
Tachibana didn't aim for Chitose's weak side because Tachibana doesn't have the killer instinct. This is why Chitose is better than Tachibana.
If Tachibana acquired the killer instinct and went after Chitose's weak side, then he may win. But at the present time he doesn't have that instinct.
The results of the match show Chitose > Tachibana.
