We used to redirect RSUltimate customers who used IE to here.
But anyway...
Chrome - good for daily browser with no annoying updates/pop-ups
Firefox - still a good secondary browser, good customizations, annoying with updates
Internet Explorer 10 - Suprisingly good for Windows 8 w/ Touch enabled
Internet Exploer 9 - Still a joke, upgrade to 10 at least
Opera - It's like Firefox's little brother that's more annoying for me, but has useful features for slow internets
