Both watches are essentially equal in wearability (I.e. size, dress up/down) and are inverted in the sense of their symmetry (I.e. horizontal plane subdials on the up/down vs vertical on the moonhpase) but have the same “busyness” in that sense to me. I think either you could easily dress up or down with a change of the strap, they are both gold "dress’ watches, but that doesn’t mean they aren’t suitable for everyday wear! I wear my dress watches with everything, only person who will care is you lol.

The up/down seems to add a bit more diversity to your collection being a manual wind (the winding of a Lange is one of the nicest winds out there) and you’ve said it yourself you like the dial layout better and movement display. Seems like you’re leaning towards that model already so go with your gut.
