I use OpenEmbedded for my projects, but I never recommend it to beginners as the place to start. Buildroot is unquestionably easier to get started with and use for one-off projects (unless you're trying to use vendor-provided Yocto/OE layers, in which case obviously it's not an option).
The article's conclusion about Yocto is spot-on, in my opinion: If you're quickly iterating, Buildroot is the way to go.
I don't really see it in the article.
