How do you rank a browser?  

How exactly do you rank a browser? I want to start a page comparing browsers, and I want to see what the order of importance the various features of a browser are. Please rank these in the order of your preference:
i) Web page viewability and rendering
ii) Compliance to web standards
iii)Security
iv) Features like extensions, mouse gestures etc
v)Speed.
It would also be helpful if you could give the extent to which these features are important so that all together add up to 100%. For example Webpage viewability-10% Standards-10% Security 70% Features 5% Spped-5%. The above is just an example. You will differ and I want to see exactly what is important to whom.
