yes, i used to agree completely with that, but now i prefer phoenix. i think phoenix and mozilla have all the features that opera has, and a couple more, so long as you install the prefbar addon.
The other benefit of using mozilla or phoenix is that the browser is open source, and it gets updated faster than opera, and it's also free. mozilla really wasn't as good as opera a year ago, and now it has surpassed it, and that's coming from somebody who used to see opera as the world's saviour from internet exploder.
