Personally from my experience with internet surfing on the Pi (despite what people may say) Chromium is by far the best on a fully overclocked Pi. Midori is just hopeless, word of advice dont sign in to chrome it slows things up! Lets be honest, with its processor and little ram it is impossible to replicate the internet speed we have become accustomed to on our modern gadgets.
I would advise not using the Pi to browse the internet on the default rasberian image, if anybody is desperate for fast internet I recommend Pidora, its internet speed is far superior on the Pi!
You could say my love for Linux is terminal
