The biggest difference is that E4 is a combined fleet map, whereas E5 is a single.

It means you must sortie 12 ships to E4 (unless you can make a combined fleet with less), but can sortie just 1 for E5.

So yes, E4D can be another spot for ranking land planes, but you'll spend a bit more resources.
