We're all sharing the same links, articles, jokes, memes, ideas, cat pictures. What differentiates a place is its sense of community, not its content. It's easy to forget that because Twitter long ago stopped being a community.
Speaking for the fediverse only, the experience is what you make of it. Stay on the largest, averagest instance and your experience will be bland; get on an instance with people who share your values, an instance that connects with other instances OK with you, follow accounts posting content you want to see and the experience will be much better.
