FAQ: Why use a source-based distribution like Gentoo or Funtoo Linux, instead of a binary distro?
Using a source-based Linux distribution like Funtoo Linux could be likened to driving an exotic sports car. It's an experience that is appreciated by professionals and technology enthusiasts because it simply offers a more direct, engaging experience with the underlying technology. You can push the technology further. You have more control. It is more satisfying.
If you aren't looking for something "special", there are a number of binary-only Linux distributions to choose from. They will get you from point A to point B. You won't have as much fun or be as connected to what's going on, nor as much control, but maybe that's not what you're looking for.
