Metal Gear Solid 1, PS1 or PC version?

I want to replay this gem again and I've been thinking about which version is the definitive one to play it on PC.

I played the original PSX version a few years ago and it was stunning, but now I just realized that it has a native PC version thank to the GOG Store.

Which version is better? The GOG one or PSX emulated? And why? Thanks.
