Twin Snakes: Good (not great) graphics, new player abilities. Over the top cutscenes. Some out of place music (like Sniper Wolfe's finale). Voice acting isn't as good--despite most of the same voice actors. Bad enemy AI.
MGS1: Horrendous graphics. Solid but lacking gameplay. Terrible enemy AI. Same great storyline. Perfectly acted cutscenes.
Yet I voted for both. Combine the two and you get one hell of an experience. I'd go with the Gamecube version if the PS1 version's Sniper Wolfe, Grey Fox, Metal Gear Rex scenes weren't so awesome.
