I would go with the 5970R, my reasons being that I like the slightly larger case, which I guess should make the dial appear less cramped thus more legible to read. And I too prefer the rectangular shaped pushers over the round one's.
Perhaps you could set a daily reminder on your phone, just to remind you to wind this very beautiful & classic Patek?
Miles, as usual your photos look absolutely marvellous.
