550D gives you better movie mode, a bit more megapixel and advance Metering Mode, In 550D you can use EF and EF-S lenses but in D3100 you can only use Nikon F mount lenses, The best part of Nikon D3100 is cheaper than 550D and will give you almost the same image quality as 550D.
Decide yourself which one will be more better as you first entry level DSLR camera, hope you enjoy this article.

All three cameras made for serious photographer, Choosing between these cameras, therefore, is not as easy, however if you see the features and sensor score (DxO Mark Lab) Canon G12 is a clear winner among these three camera. If I need a travel camera, I will go for Canon G12.
DxOMark has been updated for 2011 with several new features, new reviews and more lens and camera measurements.
There are also new, easy to digest views and scores that put the headlines front and center.
The DxOMark 2011’s key features include:
A new ranking system for lenses that comes as a direct response to visitor’s feedback;
Easier navigation and data access from Home to measurement pages;
200+ new lens/camera combinations – making a total of 1,000 available on the site!
As you likely know, DxOMark measurements are generated to improve the performance of products like DxO Optics Pro and rely on DxO Analyzer, the world’s leading turn-key laboratory solution for image quality evaluation. Thanks to its accuracy, completeness, and reliability, DxO Analyzer has become the reference tool for numerous leading imaging industry players.
its image quality is really good and, considering that the camera is now made with a plastic shell, it still feels robust and well put together. If Canon would just lower the price by $150 or so, then I’d say this was an ideal upgrade to those users with a Rebel camera
The 18 megapixel CMOS sensor and expanded ISO range produce virtually no visible noise at all from ISO 100 all the way up to ISO 1600, with even the three faster settings of 3200-12800 producing perfectly usable images. All other image quality aspects are up to Canon’s usual high standards, so top marks go to the 60D in this department.
while the 60D aims for casual shooters, it offers near professional – or should I say near-7D – capabilities and quality, making the 60D a highly recommended DSLR for anyone who just want more than an entry level model but does not need a professional tool
I did test again (earlier one here: http://vimeo.com/16196365) to address two complaints about the earlier test, the white balance and the focus. The white balance was set to Auto before, leading to two different color temperatures. This time I set the white balance on both to 3300k (3330k on the Nikon, because it doesn’t have 3300k). Also, some people thought that the Canon looked improbably soft in comparison to the Nikon, so I made sure to triple check the focus this time. Both lenses are set to infinity and looked focused through the viewfinder and when zoomed in on the LCD.
The lenses are the same Zeiss Distagon 35mm f/2 on each camera. The tripods are also the same.
Thanks to Marco for taking the time to provide his technical expertise.
I posted more thoughts about the test on Adorama’s blog (http://bit.ly/9OEOzu) and my own Tumblr (nathanleebush.tumblr.com).

Quick Guide: About Sensor Channel
Sensor Channel are the output data lane from sensor… 8 is better than 4 since it can transfer more data at the same time….The faster the camera can get the data off the sensor the faster it can fire the next shot.. resulting more fps (frames per second) in continuous brust/shooting mode.
