The newer Revell kit is far better (it has interior panels and details) and should be easy to find as it's only a few years old. It has a mufti-piece body but builds up easily with the seams at the 1:1 panel seams. Thee detail far out weighs the Hasegawa kit.
The Hasegawa kit is older but still a good one. The problem as I see it is they are charging outrageous prices for what is an old, reissued kit and no longer worth the money.
Here's a link to a build I'm still on of the Hasegawa 23 window.
