So my thoughts for today: Should I farm 12-3 or 12-5 now that I can easily clear both? 12-3 clears a lot faster since the mobs are weaker and it seems to be much easier to get 5 chests in 12-3. Is 12-5 worth it at all?

Well, 12-5 has the highest stamina ratio to the resources you can get. I've changed to 12-5 since a while ago, and yes it takes much longer to clear. I've not tried comparing bonus stage % but it feels the same. As for chest, in 12-5 I get 4 or 5 chests almost all the time.
