Imma be real, I find a lot of TNG ugly. The interior of the Enterprise-D looks like it was designed by the same people who design chain hotels. The lighting everywhere is blaring. The bridge has a weird layout. The uniforms are ugly. It’s a great show, but I don’t enjoy the aesthetics. It’s not about the ability to make modern effects, but the aesthetic choices.

Voyager to me defines a better look. The interiors of the ship have more blues, metallics, and cool grey tones. The lighting is more subdued without being grimdark. The Voyager or DS9 era uniforms both look much better.

DS9 was intentionally ugly, and I don’t mind. The station isn’t supposed to represent Federation aesthetics, and it goes with it. Even so, the dimmer lighting makes it less overwhelming.

TOS people now might say is ugly but I give it quite a pass due to the age. The uniforms don’t look great on close inspection, but I still like them more than the TNG ones. The smaller bridge feels cramped compared to TNG, but it again makes sense for the setting.
