This browser has worked the best for me and i will rank it the number one web browser.
Why? I have got endless reasons, just keep counting. This is free, opera provides excellent standards support, i have found it to be the fastest browser i have ever used, it is the most stable browser with no crashes(at least in my case), provides advanced features like tabbed browsing(means if multiple WebPages opened simultaneously it opens them in dockable windows inside a single instance of the application), there is an integrated Google search option, the page zoom feature (which allows to zoom in the entire document instead of just the text), shortcuts to turn off style sheets and images and lot more.
All this makes it an excellent browser but i have faced a few problems also. Since it is new and not that popular i have come across websites which are better viewed in Internet Explorer or Firefox. Also it is difficult to find plug-ins for this browser. But still i am sure this is the browser of next generation.
