I agree with this, but have a (maybe related) comment/question. This may be naive, but having used various WebKit browsers as well as Firefox, one aspect of the discussion that seems to be missing is end user extensibility. I notice that none the WebKit browsers support the customization that is present in Firefox (or other Gecko browsers, for that matter). This has mattered a lot to me for features like those provided by KeySnail (giving Firefox a very Emacs-like set of keybindings), Firebug, Greasemonkey and Stylish. I suspect, though I haven't confirmed, that WebKit simply doesn't support certain kinds of extensibility along these lines. Regardless, I think advocating a monoculture where such a situation might arise is myopic. In fact, I doubt Chrome would be what it is today without Firefox...it seems that its extension system is clearly based on Greasemonkey and its development tools were inspired by Firebug.
