Firstly Primal has the best interface of any app on the planet

Primal also has Zaps available and its own Lightning wallet built in

Damus good for Gifs, posting is smoother as u get a double post sometimes on Primal… Damus notifications are better

I use both as they’re both useful

That’s main difference 

 For example
