I think that depends on how you're measuring "good". STC isn't supposed to look realistic. It was conceived as a continuation of TOS, and as such tried to look as much like TOS as possible. I think, in that regard, they were extremely successful, and if that's what you were looking for, that I think STC is very good. By contrast, Prelude was conceived with modern visual effects and production standards in mind, so if you're not paying attention to how good a job STC does of copying the Original Series aesthetic, it can feel like Prelude has better production quality, even though they're both basically on par with each other. It's really kind of an apples to oranges comparison, when you think about it.Without sounding like I am knocking their time and effort, but continues , and all the other fan productions did not come close to looking any way as good as the short prelude to axanar show.
