I tried Kbin and its way harder for me somehow searching other federated instanced content on Kbin than on lemmy.

It feels like for Kbin you need to go first to lets say Lemmy.world and then check the list and copy the names of each then search it.

on any lemmy instance i can simply search the things and find stuff of other instances way easier.

also Lemmy is like WAY bigger of user base posts and comments.
