I was introduced to Concrete5 (http://concrete5.org) more than a year ago. I stopped looking elsewhere after that.

It is by far the best open source CMS. It is being actively developed, MVC backend, and the in-line editing - clients love it.

It has some good caching as well.

That's great to hear that Concrete5 is working so well for you! I'd be interested to hear more about the "inline" editing feature.
