1. The TOS Enterprise is my one, big starship love. It shaped me. It defined for me what a futuristic starship is and how it should work and what it does. I love everything about it.
2. The TOS movie refit. Same thing, just better. You don't actually get to know her as well during the movies, but the emotional connection spills over. I actallually prefer the sets (especially the bridge) from the "A"-version over the refit.
3. The NX-01. ENT isn't my favourite Trek series. But it feels as if you know this ship indside and out after watching it. I think ENT was the best in portraying the starship as a palpatable piece of technology. Which made it ever so more meaningfull when you actually got attached to it over time.
4. The Ent-E. Especially on the inside, it feels as homely as the D, but also a bit more like a real starship.
5. The Ent-D: I LOVE TNG. Almost as much as TOS. Definitely my #2 Trek series, some days they're tied for me. And the sets - the corridors, the crew quarters, ten-forward - feel as familiar as if you lived in there yourself. It's "home", probably even more than on any other Trek show. But I never liked the bridge, and the starship itself has a few weird design choices as well (Never liked the D's warp nacelles, and the lack of a bigger shuttlebay always struck me as odd. Even the TOS Enterprise felt more like a "real" starship that actually got built in the future).
6. The Kelvin-Enterprise (not the Beyond refit, nor the "A", just the original JJ-prise): It's a great new interpretation of the TOS one. She has weird size issues. But both from the outside and the inside, it felt immediately familiar.
All the other ones (Discovery, Disco-prise, Ent-B, -C, -F, the Kelvin refit/Kelvin-A): They're just models for me. Not bad ones. But I don't have an emotional connection to any of them, like I do for the other ones and the Voyager and Defiant.
