D5100 beats K-5?!

While both K-5 and D5100 (and D7000 for that matter) uses the same sensor from SONY, I think it's a bit like comparing apples to oranges. It would be more relevant to compare K-5 to D7000 or D5100 to K-r or even K-30.  Pentax K-5 has a definitive edge if rugged build and weather sealing is a strong need, while D7000 also has excellent build quality and decent weather sealing, perhpas not as stout as K-5. I think image quality between K-5, D5100/D7000 are essentially comparable since all three uses the same SONY sensor. 

While I find K-5 very appealing if you are not going to purchase extensive additional lenses, the reason Nikon gets the nod is because you get more extensive choice of lenses (although some may argue Pentax has even more choices among legacy lenses).  And if you wanted to use off-camera, multiple flash set up, then Pentax has nothing similar to Nikon CLS.  If maximum bang for the buck is your primary consideration, D5100 for under $500 is unbeatable among DSLRs. 

I'd buy it again if i had to. If you don't need weather sealing, 100% ovf , higher burst speed, then D5100 (with the same picture output as the K-5 and half the price) wins

No contest, but it costs more... would the algorithms counter this in!? I think Sortable are trying to give a different way of reviewing cameras to DPR... simple spec based with feeds. The infographic style is nice and simple; if you frequent DPR I don't think this is trying to compete. K5 though, there's some bugs crawling around! Epic. It's a tank, would blow the D5100 apart. Chuck Norris uses a K5.

The really weird part is if you go to their sister website it says the K-5 wins by a large margin over the D5100. Now THAT makes no sense at all.
