Its a very nice browser. I like it a lot better than Safari. Obviously a few bugs, but overall I like it.
The only reason I still use Firefox is because of I have a lot of addons. Aside from that, its just pure habit to use FF.
Chrome dev channel has working addons just fine, including adblock adblock+ all that. The arguments for Firefox because of its addons are moot at this point. Most of the best have already been ported, theres even a version of firebug for chrome.
Awesome bar? Anyone who cares about awesome bar apparently hasn't played with chrome bar at all, has all the same features and some that are better, including support for search engines that aren't google (ie. type yahoo searchstring and get results in yahoo).
The session is always saved in Safari, without even asking you.
If you go to the top menu History->Reopen All Windows from Last Session
Chrome does this with its recently closed tabs when you click that + to make a new tab no sweat.
As for stuff the others don't have how about built in bookmark synching with your google account, thats saved in google docs, so hey you can use them in whatever browser really. How bout intuitive keyboard controls, why pinch when you can command + and -. Check out the keyboard controls sometime.
How about tight integration with google apps, like opening pdfs in google docs instead of adobe plugin?
Then theres speed naturally, which everyone already knows chrome wins there hands down.
Reliability? I'm using the dev channel version I have yet to hit a crash and I use it for all my browsing. Keep in mind each tab in chrome is a separate process, which is a far more reliable model than other tabbed browsers.
Beta? Gmail was in beta for years, google never knew how to use the word beta right in regards to software.
As for the spying, do you use a search engine? Your data is being collected by someone. Google is a ad revenue based company, they care about your individual data only so much as it helps them generate ad revenue. They don't care about people, they care about demographics, and so does any other search engine you are going to find thats good for anything.
I do prefer chrome at the moment, but I would switch away the minute something else came along that had better features. I'm a fan of whatever does the job best, and for me at the moment its chrome.
