The kernel section is confused or just wrong. Arch has you use pacstrap to install a pre-built kernel (there are options from almost-vanilla to more custom), whereas Gentoo gives you the choice of using vanilla or Gentoo kernel sources (optionally with custom configuration) or just using a pre-built binary.
The Gentoo wiki used to be the gold standard, even for non-Gentoo users, but it was an unofficial wiki and a hard-drive crash (if memory serves) killed it with no backups. It was mostly restored with help after that.
Nowadays, I think more people use the Arch wiki.
Gentoo has package binaries available, although that's a newer thing and if you use unusual USE flags you'll need to compile your own anyway.
By default, Gentoo uses the older sysvinit system
Weird to put it this way, since Gentoo is well known for its use of OpenRC which is what you'd use instead of systemd. Both are common on Gentoo systems.
I'm stopping here - the whole article feels off, perhaps it's AI-written? I'd recommend finding a better source.
Ha, yeah - the Arch wiki calls it a "service manager" although OpenRC describes itself as a "dependency-based init system". When I wrote that reply I'd started to be more pedantic about the terms but changed it to reflect my core problem that it's not an apples-to-apples comparison to compare all of systemd to the underlying init system (you see loads of "are you using OpenRC or systemd" posts but never systemd vs sysvinit).

Rip, it would've been nice if Gentoo's docs were better than/highly competitive against Arch's docs. As a fan of Arch I often refer people over to the Arch Wiki however there are instances when I or my customers encounter incomplete/missing sections that then requires us to scour through SO or other forums for troubleshooting

Yeah I also found that really odd as it made me question if I remembered OpenRC being an Init system or not

it seems likely, although I can't confirm for sure as I only have hands-on exp with Arch either way

I think it's fair to say that the Arch wiki is larger and covers more areas, but if there's a Gentoo page on the same topic, the Gentoo one will be as good/better.
Arch is more popular, and so has more contributors (e.g. recent edits for Gentoo vs Arch).
