If you intend to build either kit as named ie. Hornet will be Hornet, Essex will be Essex, historically, I vote for the Hornet. A) Doolittle raid, B) Midway, C) Solomon Islands campaign. She was one of the ships which held the line. Essex and her sisters were the ones which took the fight to the enemy. The reviews of both kits has been favorable. Essex did serve well, but several sisters have better, ie saw more action than she did. You have a tough choice, both are important ships and both kits are above average.
