Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S6100 is significantly lighter (147g ) than the Panasonic ZS70 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS70 (Lumix DC-TZ90) nor Nikon Coolpix S6100 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 ZS70 and Nikon S6100's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic ZS70 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Nikon S6100 has a fixed type screen which provides less flexibility in shooting positions compared to ZS70.
