that's very subjective i suppose, i don't have much to compare it to. if by fun you mean stickers and animated emojis. sure. it doesn't get in my way. it is possible to find groups and people through searching for keywords.
i can name my contacts as i like. (which matrix/element for example does not allow, and that's a real problem)
the only thing annoying is that anyone can just talk to me, whereas eg. in wechat people have to make a contact request before they can talk to me directly. but i have the impression that wechat is the unusual one here, which a feature that i'd like to see adapted by other messengers too.
i also miss wechat's feature of being able to choose a custom name for myself in each group. but again, i don't know if any other messenger offers that.
