HDR (High Dynamic Range) photos
This device has HDR (High Dynamic Range). It enables the cam to combine the images with multiple exposures into a single one. With HDR, you shoot impressive photos which captures both brights and darks really well.
More focus points
Nikon D5100 has 2 more focus points
Video Auto-Focus (AF)
Canon EOS 600D doesn't have auto-focus ability while you record videos.
Much more durable battery
Starting wth a fully charged battery, you can take more shots (about 50% more) with this cam.
Faster continuous shots
It is 8% easier to catch the right moment in sports, or while shooting a rapidly moving object.
Shorter shutter lag
Shutter lag is the duration between the moment you click the shutter button on the cam and the time shutter starts to move. It is important to catch the exact moment you feel and also important for the fluency of your continuous auto shoots. Two model have almost similar shutter lags.
Faster start up
Starts up faster about 67%
Better crop factor
These are not full frame cameras (35mm). However, this cam has a bigger sensor so that cam will crop the image injected through the lens lesser. (Especially, it is very important in wide angle lenses)
Higher Max ISO Boost
Nikon D5100 has ISO Boost which helps to shoot brighter images in very low light situations (This may increase the grain)
Greater pixel size
Pixel size (measured in µm2) is the area of a singular pixel in the sensor. Bigger pixel leads to better pictures in higher ISO rates. Nikon D5100 has 24% bigger pixels.
23.6x15.6 mm APS-C
22.3x14.9 mm APS-C
Bigger sensor means more light capture area and leads to better photography. It is one the most important aspects of a camera. Nikon D5100 has 11% larger sensor area.
A little bit lighter
Almost the same
Higher resolution cam
Shoot 11% detailed photos for bigger and high quality print-outs

Higher native resolution
5184 x 3456
4928 x 3264
Native resolution is the width and height of images that is captured by the sensor measured in pixels before any processing. Canon EOS 600D has 11% higher resolution.
Higher true resolution
True resolution is effected by the physical restrictions of sensor size, and it may differ from the megapixels announced by manufacturers. Canon EOS 600D has 11% higher resolution.
Viewfinder size factor
The images you see through the viewfinder seem smaller than the ones you see with a naked eye. The closer it is to the actual view, it is easier for you to take the right picture.
RAW is a raw format, often used by professional photographers, that keeps more information about the photo as explosure, light, color details which needs to be processed on computer.
