I am enjoying all the responses. I am happy that I don't have to use Hangouts as my default messenger app, but I can still text through a Hangout.
What I like about Handcent that Hangouts does not have is a time delay in sending a text and it has scheduled texts, as well as a large selection of skins. I am sure most of us have sent the wrong person a text. The time delay gives you a chance to stop a message from going out. Also, Handcent uses the iPhone emojis, which in my opinion are much nicer than the emojis used by Hangouts/Google.
And on the subject of Google Plus, I am so happy finally iPhones can be seen in Locations. They were seen in Latitude and it took Google quite some time before Locations worked like Latitude and included iPhones.
