What's the best way to install command line utilities such as GIT?

Question

I'm a Windows/Linux guy that just got my Macbook Air. I do web dev, and am currently trying to setup this machine for some on-the-go development.

After some research attempts, I'm wondering: what's the best way to install command line utilities in Lion, such as GIT? Best as in easiest to install, maintain, upgrade etc.

As I understand it, there are some alternatives: macports, homebrew etc. Or in the GIT example, maybe just download the installer from their website.

Thanks.
