TLDR: which is better? it depends

RedHat's style guide is far more detailed and closer to a reference/explanation (i.e. going by Diátaxis definition).

Google's technical writing is shorter and closer to tutorial/how-to guide.

I recommend the Google's technical writing if you're a coder or a beginner. RedHat is for folks who already know they need this on first look.

Ok I phrased it badly with "better", I wanted to know how they compare.

Your answer is perfect, thank you!
