Chrome is great, yeah it doesn't use Apple's Nitro Javascript like Safari does, so its a little slower, its barely noticeable.
Running Chrome with a jailbreak makes it ever better. Allowing you to use Chrome as your primary browser, and the ability to run Adblocker. Such a great combination.
And I just noticed this morning using the Facebook app, I clicked on a link (opening it in FB's built-in browser) and then tapped the "square-arrow" icon in the top right, it actually said "Open in Chrome". I was impressed to see the tweak actually changed that for the FB app at least. Normally it still says "Open in Safari", but it will still open in Chrome.
