Is Apple Safari for Windows the best browser for the desktop?

In a previous post, I explored the JavaScript compatibility, on my laptop, of the 5 browsers I regularly use against the ECMA's test suite. That was my first attempt at the comparison, and I didn't think much of it. I undertook that exercise again a month later, yesterday, and I can say with confidence the following:

1. Chrome, Firefox and IE fare reasonably along the same lines.
2. Opera shows a lot of holes in its implementation
3. Safari is the worst performer: crashes in the middle of the test execution, probably due to memory leak.

You can see all the detailed results in a separate web page.
