It's better.
There. Go buy one.
Just kidding. Hehe. I haven't used a Pebble, but the color screen alone was enough for me to warrant the purchase. Watchfaces are cooler for Android Wear, but other than notifications on your phone and a few useful interactions like music controls, quick searches, voice replies, and map navigation, the Pebble has a few more tricks up its sleeve since there are apps that can be developed FOR the Pebble. Plus, the Pebble has a much longer-lasting battery life becuase of the screen.
It all ends up being YOUR personal preference. I got the Moto360 and couldn't be happier, even if I have to charge it every night.
