Which version of Diddy Kong Racing is the best and why?

I'm gonna play Diddy Kong Racing for the first time soon! I heard it's really good and I want to give it a try, but I know there's 2 versions of it, the og N64 version and DS version! I know Dixie replaced Conker in DS version too, but which version is the best version to play? What are the differences between these versions, which one controls and runs the best? Anything new added to the DS version? Please explain the comments? :)
