A kitbash is taking various models and recombining them to make a new one. The Stargazer was made of two Enterprise-A models. Then Centaur from out-of-scale Reliant and Excelsior parts. The Nebula from cutting up an Enterprise-D.I think your perception of the film is colouring your opinion of the design of the ship.
I would say the same thing about you. I'm talking about aesthetics and to me it's a joke to compare Abramprise to the refit-Ent. Refit-Ent is still one of the best looking Enterprise. It's a perfect merger of Jeffries principle of function determining form with the principles of art-deco design that dominated in the 50's. People have often claim that Abramprise follows the design aesthetics at Apple but I've never seen Apple make a product that looks so disorganized. What look like what happened is the designer merged several silhouets of various Enterprises especially the D and the E to form Abramprise. That's why I call it a kitbash because that what it is.
Whatever you think of it, the new Enterprise is an orginal take on Jefferies' and Probert's Enterprises, not a kitbash.
And the Refit Enterprise has paper thin nacelle struts. It looks fragile. The STXI version does not.
