To date the PS1 is my favourite console and I return to its library from time to time with emulators.
I played the crap out of it (and just about every other gaming machine at the time) while my N64 got occasionally brought out for the odd session due to lacklustre library. Modern gaming just does not even come close overall.

Include a bunch of straightforward racing, wrestling, sports, puzzle and 2D fighting games here (e.g Street Fighter EX, Driver, FIFA).
I don't list them because while I enjoyed such games I don't consider them having the same lasting appeal, unique identity, depth nor entertainment value as the above. Take FiFA for example. Later iterations are obviously better.

In most cases the PS1 version was better than the respective N64 version.
In many cases PC ports to this console had worthwhile changes that made them worth checking out even if you had the game on PC.
Doesn't hold up anymore but was fun at the time:
Die Hard Trilogy
Die Hard Trilogy 2
Medal of Honor
Medal of Honor: Underground
007: the World is not Enough
Legacy of Kain: Soul Reaver
I don't remember if Carmageddon was any good
And there's STILL a shitload of allegedly good games I have to check out such as Rayman, Akuji the Heartless, Persona and a bunch of other JRPGs (and pray they don't have shit gameplay like Suikoden, Final Fantasy 4, Breath of Fire, Chrono Trigger and so many other ridiculously overrated "classic" JRPG shitfests).
How anyone can claim the N64 is better than the almighty PS1 is obviously ignorant. And the "muh early 3D era sucks" types are a bunch of tards. Between the incredible 3D games released on the PC in the 90s, the PS1's amazing library many being 3D, and I guess some N64 titles, early 3D games owned it. Then when the tech quickly advanced, it just all became about graphics and realism.
BRO OH NO
PC PORTS ON PS1 WERW SUPER SHIT WITH HUGE FUCKING LOADING TIMEA
AND MANY NO GAMEPLAY MOSTLY CUTSCENE GAMES LIKE MGS AND FFVII BROS THOSE WERE SHIT THEN AND NOW
