Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic S5 II X is significantly lighter (312g ) than the Panasonic S1H which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Panasonic S5 II X and Panasonic S1H have the same Leica L lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Both the S5 Mark II X and the S1H have weather sealings in their bodies, making them resistant to water and dust.
