Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S6000 is significantly lighter (52g ) than the Panasonic ZS15 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix S6000 nor Panasonic Lumix DMC-ZS15 (Lumix DMC-TZ25) 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 ZS15's 3.00" LCD screen is slightly larger than Nikon S6000's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
