This is completely my subjective opinion, but I find "early 3D" ugly. In my opinion, pixel art has aged better. In fact, some of it still looks beautiful to me. But early 3D I find almost completely unappealing.

About the only exceptions I can think of are some flightsims like SSI's Flanker (which had very complex graphics for being simply flat-shaded 3D) and the games that emulate this nowadays, like Tiny Combat Arena.
