All DSLR of any brands are good enough for many things... IQ wise, they are all excellent and nowadays all of them can take full HD movie, etc etc. So it is really up to you (the TS) to go down to the shop and have a feel of these camera, then see which one suits you the best.
Of course after awhile, people would start coming in telling you to get the brands that they supported most and other brands simply sucks big time (or in another words, not as value for money as the brand/s that they liked), so it is really up to you to see whether you would listen to them, or would you just go down to the shops and have a first hand feel of these cameras.
Also I would suggest that you do not need to care which sensor company manufacture the sensor for which camera brands... because it simply does not matter. A sensor is an important part of the camera, but it is not the only thing that matter.
All I could say is, it is not the amount of features in the camera that matters, it is if the features in the cameras suits you and if its ergonomic, price range and if the button placement, scrolls, user interface that make the most sense to you.
While you are at it... do check the mirrorless interchangeable lens cameras system up too. These systems are capable, smaller in size and pretty well though up...
