The alternative to also try out, of course, is using the instance's website on mobile, too.
After using both Toot! and Mast for a couple of days, I'd say that Toot! seems better for managing and reading timelines of who you already follow, while Mast is better at discovering new people and events.

I'll keep using both for a while to decide, but for now these are my observations so far.
