Games where you prefer the Japanese rom

[vidmouse]

Are there any games where you prefer to play the Japanese rom version over the US (or country of your choice) version?  Why? -- what is significantly different about it?

Rygar < Argus No Senshi. Different hidden items and the version I grew up playing
Black Dragon < Black Tiger. Harder, but the last boss gives you 1 million points. 'Nuff said.

I sort of prefer the Japanese version of Donkey Kong because the board layout finally makes sense!  Although, oddly enough I find the slower elevator levels harder than the regular (fast) ones that I'm used to, heh.

Donkey Kong for the same reasons as jumpman
Street Fighter (all of them) : better, less cheap AI

Puckman for the improved vandalism potential. 

And agreed on Donkey Kong.  It's like playing the enhanced Dragon's Lair where the scenes are laid out so they actually make sense.
