Firstly, the Samsung isn't a DSLR.
Opinions vary, but IMHO the only thing that comes close to a Canon is a Nikon.
The most important element in a camera is the lens. Next is the sensor so, as you say, mega-pixels isn't always a good guide as to best quality.
Hopefully HSSutton will respond and give you a more expert, balanced opinion but, in the meantime, I hope this helps
