Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-ZS15 is significantly lighter (75g ) than the Panasonic ZS3 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Casio Exilim EX-ZS15 nor Panasonic Lumix DMC-ZS3 (Lumix DMC-TZ7) 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
Panasonic ZS3's 3.00" LCD screen is slightly larger than Casio EX-ZS15's screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
