I just ran the css3test on IE10 and the latest versions of Chrome and FireFox. None of them did well.
IE10 was last at 54%, but FireFox only got a 55% and Chrome a 63% score. So saying that the other browsers are so much more compliant really isn't a fair statement there.
I also ran the html5test on all of the browsers. Again, IE was last at 320 out of 500 points, and Chrome did much better with 448, but FireFox only got 386. That's 64% for IE, 77% for FireFox and almost 90% for Chrome.
So yeah, the other two are significantly better when it comes to html5, though to be fair, html5 only became a recommendation in December of 2012.
From the numbers overall, though, none of the browsers do a great job of supporting the standards. Only Chrome got a 90% (and barely that, it was 89.6%) in html5. All three browsers would have gotten an F letter grade in css3.
So saying that IE is so awful while the others are so great really doesn't come off as fair to me.
Just to re-re-emphasize, I use Chrome, not IE, so I'm no IE fan, I just don't get the IE-bashing when the numbers show that none of the browsers are really that great.
