It's as easy as you make it, honestly. If you have patience to read the wiki before trying different things then it's for you, especially if you want a lean, clean system with only the stuff you choose and want in it, and the latest versions of those things.
You can install GNOME or KDE and be done forever, or you could be like me, continuously tweaking my custom UI written in eww widgets, constantly optimizing my scripts, my key bindings... Experimenting with different window managers...
I make it neverending because I choose to, not because it's Arch.
I hope you join the family some day. We're enjoying ourselves.
