You're not going to hear any argument from me. I think by the time of the 16-bit consoles in particular, both the artistry and the technology behind 2-D graphics had reached a kind of acceptable baseline standard where even if they would obviously cease to be stunning with the passing of time, they would rarely be rendered completely obsolete or outright ugly (there are obviously exceptions, but generally you're talking about games that were ugly to begin with). But I'm not sure 3-D games (at least realtime, fully 3-D games) really reached a similar point until the Dreamcast, so there are few fully 3-D games from before then that I feel have aged particularly gracefully.

I can recognise what constitutes "good PS1 3-D graphics" versus "bad PS1 3-D graphics" having lived through the era, of course, but honestly I'm just not sure that the technology was there in the consoles at the time, and it all looks pretty ugly to me these days.
It's doubly problematic given that the problem isn't just one of technology, but of developers in that era still learning how to build and design 3-D games. By the time you got to the SNES, developers had something like 20 years of development of 2-D gaming to draw upon and learn from, so even many early titles played pretty well. 3-D games, though, were pretty new territory for most console developers during the early days of the PS1 era, and I'm not sure there was even really a firm idea in place of what typical genres should play like in 3-D. So a lot of it was probably the same sort of trial and error that marked the early days of 2-D gaming, and while there was the odd game that got things right, I think a huge chunk of 3-D games from that era are almost unplayably dated even if you look past graphics.

It's telling that a lot of the 3-D titles that people still play from that era are RPGs, as it was probably the genre that suffered least from the growing pains that marked the switch from 2-D to 3-D. I really loved that era of gaming, and I can say without doubt that it was easily the most exciting to me personally, but there's a huge swathe of games from it which, though I remember them fondly, I can safely say I'll never, ever revisit. ._.
