Which digital camera is better overall?

I am looking at two different cameras. One being the Sony Cybershot DSC-W80 and the other, the Casio EX-Z77. There are certain things that I like about each. The size of the Casio is very appealing but I like the metal looking effect of the Sony. However, I am more concerned about the image quality than the looks. I ume the Sony is better in overall image quality but the Casio offers better zoom capability and there are also more preset "best shot" options. The Sony has more ISO options and should perform better in low-light situations. I will also be recording videos with the camera and would like to get the best quality and longest recording time. Casio's YouTube capture mode doesn't really appeal to me since I do not upload movies to YouTube. I am really unsure which camera is better and any help is appreciated. Thanks!
