Bridge for sure. Solely due to the Edgeworth part.

I say Turnabout for Tomorrow. Probably the darkest case in the game, it had two trials, we got to see Edgeworth again, there wasn’t any of that spirit medium bullshit, and we got to arrest the best villain in the game along with a hostage scenario. Also, it was the only trial that actually made me feel emotion, AA usually over does it when it comes to sad parts of games, but they really nailed it in TfT.

Farewell, My Turnabout, because with its mind games it really left me in a cold sweat.
