Chrome is number one, Safari is number two, all others are no. When looking at speed, standard compliance, and usability, no other browsers start to come close. Firefox is third, but a weak third, like a race were two people end at almost the same time, and then another guy comes in ten seconds latter.
For reference, internet explorer is the overweight guy who tripped and fell face first into the mud.
Also, as far as security goes, all browsers have flaws that allow them to be hacked by professionals in competitions, but the way Chrome works prevents the hacker from being able to do anything. Though as far as every day browsing safari is safe too, but Internet Explorer is a no no.
