Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic G9 is significantly lighter (107g ) than the Nikon D7100 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 have to also take into account the lenses that you will be using with these bodies. Since Nikon D7100 has an APS-C sized sensor and Panasonic G9 has a smaller Four Thirds sensor, Panasonic G9's lenses for a similar focal length and aperture will generally be lighter and smaller than the Nikon D7100 lenses.

Weather Sealing
Both G9 and D7100 have weather sealings in their body, making them resistant to water and dust.
LCD Screen Size and Features
Nikon D7100's 3.2" LCD screen is slightly larger than Panasonic G9's 3" screen.
On the other hand, Panasonic G9 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, Nikon D7100 has a fixed type screen which provides almost no flexibility in shooting positions compared to G9.
Panasonic G9 has a 20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Nikon D7100 has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor .
Another similarity between these two cameras is that both Nikon D7100 and Panasonic G9 sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Sensor Size and Resolution Comparison image of Panasonic G9 and Nikon D7100 Cameras
As seen above, Nikon D7100 has a 1.6x Larger sensor area than Panasonic G9. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Nikon D7100 has an advantage over Panasonic G9 There are 309 lenses for Nikon D7100's Nikon F mount, on the other hand there are only 107 lenses for Panasonic G9's Micro Four Thirds lens mount.
Another important factor is the availability of image stabilization. Panasonic G9 has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. G9's built-in Image stabilization system is effective to compensate vibration up to 6.5-stops according to CIPA standards.106 lenses for Nikon F mount with Optical Image Stabilization features.
