We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Sony Alpha 9 II has a 3.0" screen with 1,440k dot resolution and Fujifilm GFX 100 II has a 3.2" screen with 2,360k dots resolution. Both have Tilting screens. Tilting screen makes cameras very useful for photography purposes but not so useful for video shooting. Both models feature touchscreen which has advantages such as easy menu navigation, intuitive controls, quick setting adjustment and most importantly a Touch-to-Focus functionality allowing users to select a specific point on the screen where they want the camera to focus. This feature can be helpful for achieving precise focus in both photo and video recording.

Viewfinder

Sony Alpha 9 II has a built-in 0.5" Electronic (OLED) viewfinder with 3,686k dot resolution and Fujifilm GFX 100 II has a built-in 0.64" Electronic (OLED) viewfinder with 9,440k dots resolution. They both have 100% coverage.

Sony Alpha 9 II features a 24.2 megapixel Full Frame Stacked CMOS sensor with dimensions of 35.6 x 23.8 mm and a total area of 847.3 mm². Its native ISO range is 100 - 51,200 and expands to 50 - 204,800 in boosted mode. Fujifilm GFX 100 II features a 102 megapixel Medium Format BSI-CMOS sensor with dimensions of 43.8 x 32.9 mm and a total area of 1082.4 mm². Its native ISO range is Still: 80 - 12,800
Movie: 100 - 12,800 and expands to Still: 40 - 102,800
Movie: 100 - 25,600 in boosted mode.

Sony Alpha 9 II has Stacked CMOS sensor. The key feature of such sensor is its three-dimensional structure, which consists of multiple layers of semiconductor material and circuitry stacked on top of each other. This allows the sensor to have dedicated layers for image capture and signal processing. This separation allows for faster data readout, reducing rolling shutter effects and enabling high-speed shooting and video recording. It is also more power-efficient.

Fujifilm GFX 100 II has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Sony Alpha 9 II is equipped with BIONZ X processor and can take pictures up to 6000 x 4000 resolution. Fujifilm GFX 100 II is equipped with X-Processor 5 processor and can take pictures up to 11648 x 8736 resolution.

Lens Mount

Sony Alpha 9 II has Sony E lens mount and Fujifilm GFX 100 II has Fujifilm G lens mount. Due to Full Frame sensor in Sony Alpha 9 II its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length. Due to Medium Format sensor in Fujifilm GFX 100 II its crop factor is equal to 0.79x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 0.79.

No Low-Pass Filter on Fujifilm GFX 100 II

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Fujifilm GFX 100 II. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization

The cameras have a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) (5.5 stops of compensation in Sony Alpha 9 II and 8 stops of compensation in Fujifilm GFX 100 II). This means that you are still getting vibration reduction when cameras are paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

Built-in Wi-Fi

Cameras have built-in Wi-Fi (Wi-Fi 5, 802.11ac/b/g/n, 2.4/5 GHz) which allows to easily transfer photos and videos from the camera to other Wi-Fi-enabled devices, such as smartphones, tablets, printers, or computers. This eliminates the need for cables and allows for quick and convenient media sharing and social media integration. It gives you the ability to control your camera remotely using a smartphone or tablet. This is particularly useful for taking self-portraits, group shots, or capturing images in challenging conditions without having to touch the camera. Firmware updates can also be downloaded and installed wirelessly.
