The choice between the two should come down to ergonomics more than that kind of thing. If you like using the camera, you'll use it more and make better pictures with it than you would with a camera that gives technically better images.
That being said, it doesn't mean the camera can't be better in both technical image quality and ergonomics. From a very quick handle at a local store, I personally found Nikon cameras are better designed ergonomically for my hands. But I still prefer the Olympus OM-D E-M5 I own and use all the time.
To the OP, it doesn't really matter which camera you end up buying, as all current DSLR and mirrorless system cameras are great. If you're really not sure at all, an entry-level DSLR with kit lens, like the Canon EOS 100D (which I personally prefer over the 700D) or Nikon D5300 is certainly a safe bet, though I'd personally go for either the Olympus OM-D E-M10 or the Sony Alpha a6000 first. Again, it boils down to ergonomics, so go to a local camera store and try these cameras out for yourself.
