Other than the Control Center, what are the main differences between watchOS 2 and watchOS 3?

[iMore Question]

I know that the control center is getting an upgrade when watchOS 3 drops, but what are the main differences between watchOS 2 and watchOS 3?

1. Speed
2. Dock
3. Watch Faces
4. The ability to actually "write" a reply
