What don't you like about the official apps? The iPhone one is good and performant.
Stop turning Twitter into Facebook! I'm sure it increases your engagement metrics, but at some point I'll feel overengaged, realize how much time I'm wasting and quit the app completely.
Talon supports the use-case I care about: reading all the tweets from people I follow because I care about them. Twitter and Facebook both make this nearly impossible, so I don't use them directly.
