Which ones are the best?

N64 is hard to emulate, every single emulator out there for it is at most 80% compatible, some games don't work right (or at all) and most give some glitch or another. The best is probably some version of Project64.
As for the Playstation, there are a few great emulators. The most accurate is probably pSX Emulator
http://psxemulator.gazaxian.com, but it doesn't have very much support for nice graphical filters. It's very much a slimmed down, easy to use, and almost completely accurate emulator. ePSXe
http://www.epsxe.com is by far the most popular emulator today, it has great compatibility and lots of graphic filters. If your game works perfectly with ePSXe, use it, if not, use pSX.
