Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is significantly lighter (760g ) than the Fujifilm X-S1 which may become a big advantage especially on long walking trips.
Unfortunately neither Nikon Coolpix L31 nor Fujifilm X-S1 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
Fujifilm X-S1's 3" LCD screen is slightly larger than Nikon L31's 2.7" screen.
In addition to the size advantage, Fujifilm X-S1 LCD screen also has a Tilting feature
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Nikon L31 has a fixed type screen which provides less flexibility in shooting positions compared to X-S1.
