I like mastodon but the content you see is only driven by two things: the people you follow and the hashtags you follow. Basically, you follow people and hashtags to effectively create your own “algorithm.” Once I understood this and really made an effort to follow both people and hashtags that interested me, my Mastodon feed became way more interesting than my Twitter feed.
I also like the quality of the interactions better on Mastodon. Because of how the whole thing works, you’re not going to get bombarded with horrible stuff in most cases (at least the chances seem to be far less for that kind of thing happening).
But it definitely takes more time and energy to curate compared to Twitter.
