And it worked on more operating systems! I mean, firefox works on Linux, windows, and mac; but netscape worked on Linux, windows, mac, as well as windows 3.1. Obviously it's the best choice.
But seriously; for all intents and purposes, the browser war is over. It was Netscape versus IE. IE won by a large margin since netscape sorta dissolved and had to be reborn as an OSS project. Asking "which browser should I use/is the best" is akin to how women will often ask their boyfriends/husbands wether they should wear, say, the red dress or the blue dress. It doesn't make a difference which one you wear, it'll still take the same amount of time to get to your destination. A common metaphor is that the browser is that the browser is a vehicle that moves us through the web; some browsers are corvettes and others are pinto's and so forth, but this isn't the case. No matter what browser you are using, you're riding in the same car, just wearing a different dress.
