If Facebook succeeds at integrating Whatsapp to Messenger, I think they'll have a strong contender. Whatsapp is no-frills, simple texting that includes the possibility to share pictures, locations, videos, etc, whereas Messenger has all your Facebook contacts built right in.
If they can do that, and release a PC interface for Whatsapp, then I'd probably use that exclusively. But as it stands, I'm switching between Messenger, Whatsapp, Hangouts, and Kakao Talk, depending on who I talk to and what platforms I have at hand at any given time.
