I've always felt that Chrome felt more responsive and speedy. Just ftr, I am running a 13" MBP w/ a 2.4ghz C2D
EDIT: I googled the issue and found this nifty article which ran 20+ tests comparing Firefox, Opera, IE, Chrome and Safari. Unfortunately they were all tested on Win7.
SO, I decided to run a test myself on my MBP.
The test I ran was Futuremark's Peacekeeper which, according to the website, "is a free online browser benchmark tool. With Peacekeeper it’s quick and easy to compare different browsers to find out which one offers the best performance on your PC...Peacekeeper measures your browser's performance by testing its JavaScript functionality."
Results (higher number corresponds to greater performance):
Chrome 5.0.375.86
Run 1 – 5418
Run 2 – 5424
Safari 5.0 (6533.16)
Run 1 – 4068
Run 2 – 4068
Firefox 3.66
Run 1 – 2481
Run 2 – 2507
Opera 10.60
Run 1 – 4978
Run 2 – 4978
Keep in mind that these tests were run using a C2D 2.4ghz processor so people with i5/i7s will most likely post higher results. However, using this test, Chrome clearly wins but Opera is not too far behind.
