Have completely switched to IE10 since a couple of months ago, find it to be perfect for my needs now. I have never really likes Chrome as I don't use any Google services, and although I used Firefox previously I just feel that is becoming a little more bloated and inefficient.
The only minor negative to IE10 is the lack of Adblock, but I find that the Tracking Protection lists work almost as well without the need for any extra browser plugins. I know a lot of people have genuine reasons to dislike Internet Explorer, but I find it perfect for simply browsing without all the social networking obsessions becoming more prevalent in the other browsers.
