I tend to like smaller watches for the most part, or at least I dislike large watches. The DJ41 doesnt wear as large as its dimensions suggest, and I actually think it looks better proportionally than the 36. I also think the blue dial is the pick of the options and offers a really interesting composition.
The new OPs arent great, especially the ones you referenced are pretty garish, and I cant imagine a scenario where I would choose one over a DJ41. The outgoing, white dial OP39 on the other hand was pretty close to the ideal one watch, so I assume Rolex is planning a white dial Explorer in the near future to take that place.
I would pay 20% over MSRP for a white dial Explorer if it had the black surrounds like the Polar Explorer 2
