Which Mastodon client do you prefer on Android and why?

I know of:

• Tusky
• Fedilab

I don't know which of the two to use. They are quite similar in a lot of regards and I don't think I've seen all differences.

Do you prefer one or the other or another option? Why?

Requirement is that the App needs to be available on F-Droid.

thanks for your opinions.
