Our verdict

Siena, unless the tower is the point.

With one free day, pick Siena. It fills 5 to 7 hours, costs € 35.60 to € 37.60 with the train and the cathedral pass, and the bus drops you at the old town in 1 h 15. Pisa is 15 minutes closer and costs € 39.60 with the tower climb, but the square is done in 2 to 4 hours and the rest of the day needs a second plan. Pick Pisa if climbing the Leaning Tower is the one thing you came for, if it is Sunday morning, or if you want to add Lucca the same day.
