TFA uses http://jsbenchmark.celtickane.com/Run.aspx which is a joke.
A useful benchmark is Futuremark's Peacekeeper, really, since it tests a wide variety of common tasks. On my machine, Chrome's the fastest at raw JS, but (by far) slowest at rendering...besides Firefox, which is actually slowest at -every- benchmark -every- time (by a typical margin of 5-10x or more; 4 RC is even slower than everything else on its own benchmarks like Kraken).
Even Opera (with no hardware acceleration at all) beats Chrome at complex graphics and rendering on canvas. Chrome is also the only accelerated browser to get incorrect rendering/redraw on many of the various Canvas acceleration tests/demos.
IE9 is the fastest at rendering complex stuff, while still keeping up with the pack on regular JS, which I dare say is a useful area to be #1 in.
If the browser compiles all of your JS really fast, but then takes a lot of extra time to actually display it, you're still bottlenecking as if you had an incredibly slow JS engine, just at a different part in the average case.
If you do HPC in your web browser via JS, Chrome is definitely the way to go, though.
