As noted, the Acid 3 test results are widely published - of course by those who wish to tout the advantages of their favorites, or to disparage IE. But once again, benchmark tests, including the Acid 3 test, don't reflect real world usage. I have asked for those who keep referring back to the Acid 3 test to provide real world examples of sites not working with IE, but none have been presented. If it such the problem, why not? Examples should be aplenty.
If a Lamborghini can beat a Porsche to the finish line on a drag strip, does that make it a better car? If a Rolls Royce offers a smoother ride than a Lexus on the Autobahn, is the Rolls a better car? If a BMW corners better than Mercedes, is BMW a better car?
I have personally not found one site that I cannot view with IE - including my banks for Bill Pay, credit union, or my Government accounts for my retired Air Force and health insurance business - some of which did not allow access to FF last time I tried. And there have been several comments in this thread from some of you who report you "only use IE when FF does not work." Does not work? How does that make FF better? Perhaps the occasional site failing with FF is not problem for you, but for me, it would be a problem, and since I am very happy with IE's speed, FOR ME, IE is better.
I refer back to my link earlier to
PCWorld's Browser Showdown test. It did not use "benchmarks" to compare. It used,
...nine popular Web sites: Amazon, MySpace, Yahoo, PC World, YouTube, Microsoft, Apple, eBay, and Wikipedia.
We loaded each site ten times in each of the browsers and repeated the process the following day to rule out any network traffic or server issues. Prior to each test run, we cleared the browsers' caches as well. We also repeated the load tests to ensure that we had sufficient data to identify loading speed trends. To ensure consistent results, we performed testing on a fresh Windows Vista installation, and we reinstalled the operating system before each round of testing. Additionally, we removed the two best and two worst scores for each page load test to produce more consistent results.
These are about as "real world" as you can get. The conclusion,
By and large, we found that Internet Explorer 8 performed well, and beat out Firefox 3.0.7 in the majority of our time trials.
BUT
In practical, everyday use, you likely won't notice much of a difference between IE 8 and Firefox 3. Due to the fact that broadband connections are so commonplace today, and the fact that browsers in general can load pages faster than they could even a couple years ago, the page load time differences between the two are relatively moot.
