I agree, get the return sceptre. The fact that you need the golden clock for perfection is a good point, but if you're at the point where you can make 10 mil in a reasonable amount of time, then hopefully making an extra 2 mil first won't take too long. Depends on how your farm is set up, though.
IMO the statue of endless fortune's best use is that it makes birthday gifts more convenient, which is nice, I guess, but nowhere near as useful to me as the return scepter. Obviously, the value of that depends on whether you like gifting NPCs, and whether it's easy for you to get them loved gifts without the statue. The wiki says the statue of endless fortune is a good way to get iridium, but if you're at the point of having millions of g and working on completing the game, then you should be easily able to get the statue of perfection from Grandpa's shrine which will give all the iridium you need to craft stuff.
