Yes, it's a huge difference. However, you can install the very latest Google Camera app through the Aurora app (or Play Market), and it works perfectly except you don't get photo preview within that app; to fix that minor issue, you can install the Gphotoshim which someone else mentioned in the comments.

On the other hand, if you switch to the latest Google camera app, you will not really be participating in making the open source version better.
