I'd disagree. I pop open kbin.social first, and now Artemis second. When I get bored of those, I go to YouTube, Instagram, and Reddit. I'm giving the fediverse priority for my leisure attention, but there just isn't an endless supply of interesting content on the fediverse yet.
It's improving slowly as the Fediverse grows and as I dial in my communities, but it'll be a while before it's able to fully hold its own (for me).
