For one thing, the PS1 is one generation more recent than SNES, so it is going to have better games simply from game concepts evolving. If you are talking about which games were better at the time of it's release, SNES wins easily. Graphics aren't everything, some people still argue that FF6 is better than FF7 today, which means that FF6 must have been spectacular when released compared to games at it's time.
The PS1 probably would not exist if the SNES hadn't. Most, if not all, PS1 games were based on concepts that were refined during the SNES era. You name me a PS1 game and I can probably name you a SNES game it took concepts from.
Simply put, games are more refined as generations go by, but they were more original in the past.
