Comparing Canon to Nikon is a lot like comparing Chevy to Ford. It's all in the preferences. Photography is not about the camera or the maker.
I handle Nikons every day, but I wouldn't own one. I currently have 2 Canon DSLRs. My preferences in the Canon is it is a lot more user friendly. I can control both of my cameras without having to take my eye away from the view finder, and I can control them with just one hand. My experience with Nikon is the controls are on both sides of the body, where Canon has the more popular setting adjustment controls on just one side. My T3, which is a little bit of a lesser version of the T3i, has captured a lot of my more popular photographs. It doesn't have the biggest sensor, nor does it handle low light very well, but it still did the job.
Both makers are about the same to change out the lenses. Just one push of a button and turn it.
I had the Canon EOS Rebel XT - loved it but it is outdated, hence the reason I sold it on ebay.
My husband handles Nikons everyday and he prefers the Nikon over the Canon but like you said, it is all in preferences.
I bought the Nikon D3100 14.2MP Digital SLR Double-Zoom Lens Kit with 18-55mm and 55-200mm DX Zoom Lenses in a package deal paying less than $500 for all whereas the Canon Rebel in the t3 package only gets you 1 lens (18-55mm) and cost $100 more... so GW also has to consider how far he wants to dig in his pocket... because even after coughing up the money to buy the camera and len(s) you still need an extra battery, storage/flash card and maybe even a bag.
SoMD_Fun_Guy,
I bought my camera with the same thoughts you had in mind and I love the fact that I can get close up - take wide angle - etc. with my Nikon but because I'm a very busy person anyway... and don't have time to fiddle with too many details, I shoot a great deal on auto focus. These 2 pics are just shot on auto focus w/my Nikon.
