If you do a search in the forum, you will see that this is an often-asked question and it usually gets basically the same response...
Any of the DSLRs is capable of capturing excellent images. However, they all have differences in their features and differences in performance in certain areas. Only you know what you want to achieve, so only you can make the final decision. There is WAY too much information available for us to be able to provide it to you in a forum like this (even if the options are limited to just a few cameras). You should do your research to find out what the features are on the cameras you are interested in and give some thought to which features will best support your particular goals. The Popular Photography web site is a great one to start your search. Look for camera and/or lens reviews to get both objective and subjective test results - information that you can use to determine which camera models will come closest to filling all your needs.
You will also find that it is frequently recommended that you get out and handle each of the cameras you are considering. The reason for this is that each manufacturer takes a slightly different approach to the human-camera interface and some cameras will just feel more comfortable to you. You will likely find one manufacturer (or possibly even just a single camera model) where the controls seem to naturally fall under your fingers and operate in a way that is logical to YOU. When/if you find such a camera, you would be well served to buy it. You will learn faster and progress farther with a camera that you are comfortable with.
So, once you have narrowed your search to the models that contain the features you believe you need to help you capture the images you are interested in, you should take the time to hold and operate each of the models that end up on your list. Once you have done all that, you will have prepared yourself to make the final decision as to which camera to buy.
