How can a totally subjective topic be won with a 'blitz' ? They are the same in every functional way except for branding.
While I agree that it's not a 'blitz', I also don't think it's totally subjective.
I mean sure, they're equal on basic browser functionality, but you can easily compare things like program load time, web page render time and javascript execution speed quite objectively.
Personally I use both for different things, though I use Chrome the vast majority of the time. For me Chrome is a faster, leaner, cleaner, prettier browser, and Firefox is a much more customisable one.
