As someone who started out with Manjaro and used it for a bit over two years, it does its job alright.
That said, Manjaro’s “let’s use Arch repos but delay them for two weeks” policy leads to compatibility issues with the AUR.
Also, they’ve repeatedly let their certificates expire (happened like 3 or 4 times, iirc) and there’s been some management controversy, especially surrounding Jonathon leaving.
If you want “Arch, but beginner friendly”, there’s better options than Manjaro, imho.
Telegram being next to Signal is also questionable.
