Chrome is fast and minimalistic, but not fast enough to really be an alternative to browsers that don't send my information to Google. I really don't like to put anything that's even remotely linked to my real life on the internet (I don't even use paypal or facebook), so I'm really not a fan of Chrome.
Firefox is the paranoid peoples' choice.
The new version is a lot faster than the old one, plus it doesn't take ages to load anymore.
