Weather Sealing
With its weather sealed body, we believe that G1 X III has a big advantage over H90 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Canon G1 X III's 3 LCD screen is slightly larger than Pentax H90's 2.7" screen.
Moreover, Canon G1 X III sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Pentax H90 has a fixed type screen which provides almost no flexibility in shooting positions compared to G1 X III.
Canon G1 X III has a 24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Pentax H90 has a 12.0MP 1/2.3" (6.17 x 4.55 mm ) sized CCD sensor and features Prime processor.
Canon G1 X III's sensor provides 12MP more than Pentax H90'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.
