Looks like Opera now gets 100/100 on the Acid3 test, as does WebKit.

Opera’s rendering still has a few bugs and the WebKit guys are still working out the performance, but this is a great step in the right directions. Unlike Opera, which only achieved this in an internal, non-public build, you can actually download a WebKit nightly and try the test for yourself.

For those unfamiliar with the test, there is a great Wikipedia page about it. In short, it’s a test that makes sure browser are standard compliant with the latest technology in order to assure the same functionality for all the cool new stuff on all browsers. Unfortunately Internet Explorer is very very very bad about that, and Firefox isn’t that great either, so for now it’s Safari/Webkit and Opera leading the pack!

Update: Opera now has a public build out that passes Acid3 scorewise, see the two new screenshots attached above. There are still more performance problems in the Opera build than the WebKit one, so for now WebKit is ahead!
