The 4101 is the AP I would have chosen as well; too easy to go with the 'traditional' RO. The Millenary has so much wrist presence and you point out all the things I love about it: the case shape, the grey tones of the steel model, the reversed movement. And I actually like the view from the rear as well.
Interestingly, when I was in Paris recently I sort out the AP Boutique specifically to strap on the 4101 again, and it confirmed my initial feelings.
Very impressed.
