Pretty much every industry works by tricking people into liking things.

Like the razors with four+ blades on them, people buy them cause the commercials say “more blades is better”.

People wouldn’t seek out extra blades if they weren’t tricked into liking it. They are objectively worse than single blade razors.

I found Gentoo more helpful than LFS because with LFS you compile about 80 packages from source one at a time but you don’t learn too much about the packages.

LFS gave me much more awareness of what packages actually come with a Linux install but Gentoo taught me more about configuring and booting a Linux system.

Although I’d definitely recommend both to anyone wanting to learn. I’d do Gentoo first then LFS.

Edit: LFS is also a masterclass in cross compiling so if that’s something you’re curious about LFS is the way to go.
