I'm a cross platform engineer working in OS X, WIN 7, Linux & Unix. Running both the most recent builds of the stable _ and _ beta versions of Chrome on my new 15" MBP's & ThinkPads, I've found the stable versions to be very reliable & crash free. Moving on to the Beta versions, the number of crashes have been very small, especially considering how many hours of use they see each day.
I am not advocating for Google, I also put plenty of time on Safari, Opera, Firefox & the yet to be released to the public, GreaseMonkey.
Thus my point is simply to share my experience. In the last four weeks I've been using Chrome as my browser of choice, where previously it was number three on my list.
