If you're worried about using Google services, you can still use Chromium instead of Google Chrome, and disable the search suggestions features, the syncing features, and switch your default search engine to something else. That way you get a great, speedy browser, without worrying about any tampering Google has done with its own customized build of Chromium (a.k.a. Google Chrome). Besides, if you're paranoid enough, keep in mind that Chromium is an open-source project and you can spend as much time as you want reviewing the source code.
Also, the latest versions of both Chrome and Safari all pass the Acid3 test with flying colours, not just Opera. When it comes to web standards, aside from IE, all the major browsers are more or less on par with each other (and even IE is getting quite a makeover in the form of IE9).
