Ricoh WG-6 has a 20.0MP 1/2.3" (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, FujiFilm S200EXR has a 12.0MP 1/1.6-inch (8 x 6 mm ) sized CCD sensor and features EXR processor.
Ricoh WG-6's sensor provides 8MP more than FujiFilm S200EXR's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the WG-6 and S200EXR sensor size comparison.
