I like the second one, as it is more like the way the eggs would be if under a hen.  The first one looks like you can get more eggs in it.  So perhaps use the second one unless you are incubating more eggs than the second one can handle.
Nice job on them by the way.
If that was my set up, I would make sure the fan is not blowing directly on the eggs, as it will probably cause extra loss of fluid in the egg.
