Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung WB210 is significantly lighter (32g ) than the Panasonic ZS20 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS20 (Lumix DMC-TZ30) nor Samsung WB210 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Samsung WB210's 3.50" LCD screen is slightly larger than Panasonic ZS20's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
