Hi Kyo kusanagi!
Congrats on your new discovery to start on start on the journey called photography.
Firstly, I wouldn't be so bold as to be telling people that I have fondled a model ... of a camera. Might give a wrong idea ... LOL!
Just kidding. On a serious note, buying a camera is like buying a car. End of the day, it all boils down to which one you like and can afford. And if your friends share a similar make or even model. Cos then who knows, you can share accessories! Also, make sure you have a test drive (go and FONDLE the various cameras available) to ensure that you are comfortable with a normal seat or prefer a bucket seat (the camera feels comfortable in your hands, not want your hands to be cramping after 2 hours of hand holding it during a shoot).
Also, understand what genre of driving (photography) that you want to do ... sports, just from home to office and back home with weekend outings, drive family around, etc (whether you like to take pictures of landscape, portraiture, macro, sports, general, etc) will determine if you want to fit safety or sporty accessories or just use factory fitted tyres (lenses - can start off kit lens that comes with the camera, or you want to buy additional specialised lenses for your type of shooting).
Mind boggling right?
Like cleonbus said, Canon users will say Canon is good. And you've sadly left out real DSLR manufacturers like Nikon, Pentax, Sony, and even Sigma ...
No matter which camera you choose, what matters is the basic foundation and skills that you need to take a good picture, not how to operate the camera.
Hope I have not confused you any further! If you have any other queries, just ask. But what is important is the budget you have set aside for this expensive hobby. Do let us know and we can tell you if it is enough or not, and what you can generally buy.
Cheers
