Why not both? lol
I like both but they have their own special things. Original has the 2D weirdness while remake has the weirdness translated for 3D and it adds another similar taste lol.
But remake has a cool feature of whatever clothes you wear being shown on your character and gives you another taste in combat.
In the end original is for the real taste of the art of the game, while remake is for enjoying another test of weirdness and combat.
But if you wanna get the best experience of course original is the real deal, while remake is more childish to befit modern anime kid generation I guess, but then if you don't care about the art and dislike the gameplay of the original remake is okay alternative.
