Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX20 is significantly lighter (118g ) than the Canon SX170 IS which may become a big advantage especially on long walking trips.

With its weather-sealed body, we believe that the TX20 has a big advantage over the SX170 IS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX20 and Canon SX170 IS's LCD screens have the same diagonal size of 3.00 inches.
