The larger the sensor the more light the sensor captures yielding in better image quality.

Polaroid Snap: 81.2 x 25.4mm
3. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.
Olympus OM-D E-M1 Mark II: 60fps
4. maximum light sensitivity
With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
Nikon D7500 + Nikon AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR: 1640000 ISO
5. longer battery life
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Nikon D3x: 4400shots
6. video recording
1080 x 30fps
Canon EOS 1D X Mark II: 2160 x 60fps
HTC Re: 65.5g
8. fastest shutter speed
A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.
Sony Cyber-shot DSC-RX100 IV: 1/32000s
9. has a stereo microphone
A stereo microphone allows to record audio files or movies in stereo without an external microphone.

12. has built-in optical image stabilization
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

13. has AF tracking
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
18. has continuous autofocus when recording movies
When recording movies they stay focussed and sharp.

19. screen size
The bigger the screen size is, the better the user experience.
Samsung Galaxy Camera 2: 4.8"
20. shoots raw
A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.

21. has a serial shot mode
You can shoot multiple pictures in a row.

22. has a flash
A flash is good for low-light environments, and can sometimes be used as flashlight.

23. has a CMOS sensor
CMOS image sensors are slowly replacing CCD sensors, due to reduced power consumption and better image quality. They can be very compact and cost relatively little to produce.

24. widest aperture
With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
