After having the AW since 4/24, I've realized there probably won't be one watch face to rule them all. Think the best strategy is a different watch face for different attire/situations.
I voted Simple, but I mostly rotate between three of the faces. One other poster on this thread mentioned the circular shape of the analog face on a rectangular case. Something in me also finds the clash of the two shapes to be weird. Not bad, just weird for my brain to process. Complications in the corners help a little to rectify this. I don't dislike any of the faces either.
SIMPLE: Complications in corners only, orange second hand mostly, use every time detail. Complications are smaller but appear cleaner than the shadowed complication backgrounds of the Color face.
COLOR: Complications in corners, monogram in use, float between orange and white. Like others have said, I wish the second hand could change color to match.
SOLAR: This one is very original, beautiful, minimalist futuristic, relaxing and was the one face that made me excited about the watch when it was first teased. When I want something sleek and not overwhelming with info, it's this one. I split time 50/50 between this face and the analogs.
