Opera has been one of the very well disciplined and feature-rich browsers for the longest time. It was atleast twice as fast as anything else about 8 years ago, on dial-up (ah, the good old days). It was pretty impressive what they had at that time : email integration, ability to identify as one of the other browsers, the cool tabbing system and even themes! They definitely beat the competition (navigator 4.7, IE4/5) hands down. Too bad they couldn't get the scale then.
