^^ you can only take DXO Mark so far. I bought my a700 because it had a better viewfinder than the a350, but was surprised that the image quality was MUCH better, the a700 has been fairly popular, while the a350 has been disappointing. Snapsort is better, but only when the information is accurate, and often times it isn't. Even when I can absolutely see evidence, like dpreview's resolution test stating the two are similar, real-world experience has lead me to believe that the a700 is sharper with better color with smoother gradation and better noise management than the a350. I can't really explain it, because measurements made by these trusted reviewers say it should be otherwise - and I do trust objective, scientific obersvation over hippy dippy "it just has a better aura". I'd admit it's just "lost cost" talking, but I wasn't expecting significantly better image quality, and I am very happy with the viewfinder and felt it was worth the purchase the moment I held it to my eye.
While I don't necessarily doubt that DXO Mark objectively measures real metrics of camera performance, real world use doesn't always seem to reflect this and the only way to get a feel for camera performance is to actually use it.
