As mentioned, not much difference in room design. NOthing special.
However, I will say that the bed we had in Octav this last vist was THE BEST ever.
Last 2 trips, requested and preferred Augustus, but it seems everyone has had a taste of Octavius and prefers Augustus, so at our time of check in it was a long wait for Augustus if you wanted a king bed. That tells you something.
If you don't mind 2 queen beds instead of king it might get you in Augustus faster.
Our first Octavius room had issues. This time it was OK, except as FFlowers and other said, a long walk.
Both times, the Octavius bathroom TV didn't have a remote, and only like 5 channels.
