I daily drive Arch for about 7 years, therefore I’m clearly biased. But I love Arch for the AUR and the ease of getting packages. For me, it is the best OS on desktop to get things done. For other use cases, I would probably choose a different OS, but desktop is Arch all the way.
But you’r mileage may vary.
I agree, I wouldn’t suggest arch to a newbie either, but OP said he has experience with arch
