I couldn't ever give up vi key-bindings but I liked the rest of emacs more, so I use emacs in viper-mode (comes built-in), which emulates vi. You can use emacs as a modal editor but still fall back on all the emacs functionality. For most of the time it works like the best of both worlds, but it's not perfect . You can't use viper-mode in every mode and it's obviously not full vi(m) emulation. Installing the vimpulse.el script (google it) adds a lot of missing vim functionality though.
