Same here. Algos surfacing stuff I don't care about at all (and can't turn off!), and I've run across enough instances of the official app/page not showing me some tweets (checked exhaustively for a couple days of tweets around the ones it missed, couldn't find) that I've utterly dropped the official clients.

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.
