The gentoo installation process is better documented and you learn a lot more about compilation. I started with gentoo, installed lfs for fun and years later made the switch to arch. I think I learned a lot of things I didn't know when installing lfs, but nothing new when installing arch (had used gentoo for at least 5 years at that point thought). I think that the main sticking point is the documentation. It was certainly the reason why I went with gentoo at first, not because of the control over the system, but the fact that there was a great wiki (that was often down :D) and great official documentation that lead me every step of the way. I'm of the firm believe that every linux install can teach you everything as long as the documentation doesn't skip on things. You won't learn anything from lfs if you just copy paste commands and you can at that point install ubuntu.
