Will you recommend making an Mastodon account if I already have an kbin account?

As current state, even within Fediverse, browsing contents from other Fediverse like Mastodon still does not feel quite the same. Of course, It's a different social media platform so it's expected that, you will need 1 Reddit account and 1 Twitter account. But in Fediverse, do we need to do the same?
