Thankfully I don’t have people I need on WhatsApp, but it took some convincing.
Nowadays I only have dentist and barbershop on WhatsApp, all my folks are on Telegram, including all work communications.
WhatsApp was always lacking features; WhatsApp web can’t replace a full featured desktop client which is a must have for me; and its mobile client is inconvenient in every possible way.
I was using Gentoo for some years, and I have to say I do not regret switching to Arch.
That said, power to those chosen or damned to wield Gentoo in the eternal war of kernels. They are the fabric of reality, interstellar light and darkness, they are the reason we, common folks, can live peacefully with precompiled packages, not knowing the pains of building everything from sources.
Never seen an intuitive UI. Been on Linux since 2004, was working on company-provided Macbook and struggled with UI, was very happy to abandon it. I have Windows as a gaming OS, dual boot configuration with my Arch Linux, and me tell you I game on Windows like twice a month, absurdity of this OS makes me not want to game.
For me the most intuitive UI is the one I built on Linux, with I3wm and a on lot of custom scripts. This surely will not be intuitive for you.
Universally intuitive UI is a myth.
