Gonna semi-disagree. Unless you're rolling out an old school CRT to play the game, Gamecube version via emulation holds the best today (outside of Vita on it's small screen).
- High resolution character models, ability to skip all scenes (even in-engine one's), 60 FPS FMV (I think, not 100% sure).
- Additional emulator based smoothing options which enhance, or at least smooth out, 2D background quality on higher resolutions.
Notice all the store front names, car bumpers etc to see the cleaned up aliasing on these ancient 240p backgrounds.
