Been using Chrome because it has good extension support and it's lightweight. Some native Lion features like full screen are busted, but the dev team already stated they're committed to fixing it soon.
The biggest reason I don't use Safari is the lack of a built-in search feature for the address bar. I might switch back to it though after having installed this:

That's a very useful plugin that makes Safari's address bar behave more like Chrome's. It just came out about a week ago. The search box is also removed to save space. I think Apple should adopt a native omnibar. Until then, this provides a really good solution.
Wow. Thank you. It was driving me crazy. I always typed my searches in the address bar by mistake in Safari. I'll see how that extension works. But thanks!
