Mark Fine,
Cool selection of pics, with their apparent similarities in layout and playability.
The big difference in the bunkers, apart from sand color, is the pitch, or angle at which the sand is flashed. This is, of course, by design. You can see in the bottom picture how similar the pitch of all the bunkers are. It makes for a more dramatic presentation.
Which one is better? It's a matter of personal preference, both aesthetically and playability-wise.
If I had to guess, I would say Doak is the top pic, Hanse is the bottom. I'd also say that from these two limited examples, I like both presentations equally well.
