I chose the Mastodon server to see how the overall federated system worked in general. I didn’t appreciate the choice of picking another server and learned you can’t undo your instance choice unless you create a new account. It is a different interface than Twitter/X and Facebook, but based on my experience with those platforms, it seems to have a bit of each with likes, replies and boosts, or re-tweets. It’s interesting but I think it will take some exploration to fully develop an opinion.
