Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS1 is significantly lighter (371g ) than the Canon SX20 IS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Canon PowerShot SX20 IS provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic ZS1's 2.7" LCD screen is slightly larger than Canon SX20 IS's 2.5" screen.
On the other hand, Canon SX20 IS sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Panasonic ZS1 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX20 IS.
