For me, IE9 > Chrome > Opera > FF > IE8 and older.
At Uni they have IE7 installed so I use Chrome on those machines, after using IE9 you can never go back to the old versions, they feel woefully slow.
As an aside, I tried Windows 8 CP the other day, and IE10 was absolutely amazingly fast. Very very impressive.
I do love the sheep and their IE hate though. I'm waiting for OpethDisciple to pop in with his "OMG IE SUCKS, OMG IE IS **** OMG YOU SUCK 4 USIN IT LOLZ".
