So far I've found that I use Strava, Pocket Cast, GPM All Access, and Poweramp the most on the 360. Having had a Moto X for nearly 2 years now I'm quite accustomed to giving voice commands so sending texts and searching from my watch are done frequently and fluidly.
LOL at the showoff category, I may do that. But the watch itself has drawn some attention on it's own. I was eating dinner with a table of coworkers and clients this week when a text came in on my phone/watch. One guy noticed it, asked about it, then it became a 20 minute long dog and pony show for everyone.
