I think it comes down to who you are and how you use the browser. A normal average citizen doesn't understand the term css, and probably couldn't give a definition on html, they'll only be interested in 1) ease of use and 2) visual appeal.
I too switched to IE from nav3, the ability to move and shrink IE's interface was a definate enhancement to the browsing experience. While in netscape, you were forced to have a good 1-1.5" of your screen taken up by their clunky interface. the only drawback (from the average user's perspective) was the inability to change the skin, but honestly netscape's skins really aren't that neat anyways, so it's not any loss.
having used FF, and looking at sites at the same time in IE, not to mention building a few and comparing...I'll completely agree with people here, FF is much better. not to mention FF gives me everything IE has, and more regarding ease of use and visual appeal.
for me...it's kind of like a film student and a normal person (a friend of mine and me respectively) going to a movie. Even though I find it entertaining, he'll completely tear it down for technicalities in the directing, lighting, etc.
