Image Quality?

The two are almost the same, but Nikon has a natural warmth in its shots that I haven't been able to achieve with any other camera. My opinion might be partial because I am a die-hard Nikon fan, but Sony doesn't seem to have a very practical selection of lenses either...

dxomark.com says that it is the Nikon D7000, but only by 2 points (80 vs 78). What/where would you like to take pictures? I would like a little more information before saying what is best for you.

Nikon D7000 has the best image quality in its range of DSLR cameras and its not comparable to Sony's image quality. The main reason is powerful sensor and image processor (of course if you are shooting RAW the image processor doesnt have anything to do with the image quality). Another thing you should consider is the availability of lenses for each of these choices; Nikon definitely provide you with a wider spectrum of lenses comparing to sony. The reason I brought up number of available lenses is when you put two pictures taken with these cameras beside each other you can not spot a gradual difference between them, this is where you should consider other aspects like lens availability and so on.

sony is faster , have 24mp and gps! 

I think Nikon D7000 produces best photos and if you want to be a professional photographer someday, Nikon D700 is best to start with. 

I take pictures using my D7000. Wonderful.

Nikon D7000 is outdated. Choose Sony.
