LFS eldritch horror here, I just daily Gentoo. Maintaining LFS is just exhausting and kinda unrealistic for any long term use. It's not really meant as a daily driver but more of a learning thing. But man, it's freaking awesome to see a system you built from scratch boot up and function. I highly recommend it, and even if you do/when you fail, at the minimum you learn to appreciate all the hard work that goes into a distribution.
