many feel that more detailed starships look better and/or more realistic.
It's not really detail per se, it's the execution of the detail. The level of detail of the movie-era and TNG+ era ships was higher than TOS, but few people talk about those as garish or overdone. It's the "everything and the kitchen sink" approach that has overtaken. The JJ-prise with all of its tacked on swoops and arcs is representative of today's aesthetic. It has an incoherence or randomness to it.
