Hangouts vs evolve sms

[eric002]

For an Android Wear messaging app for a watches, what's the best app for with full where compatibility use Hangouts or evolve SMS? The only problem that I found a special with the developers that they don't have Emoji support and he won't be anything anytime soon. The problem that I had seen for Hangouts is that when I put in a voice text it doesn't always update in my hangouts inbox thread list.
