In your case I would use either structs or arrays but not lists, since Lists can get quite slow with a certain size. It's allways a string operation. In CF8 structs were massively improved in performance. That's why you can use either an array or a struct. But since a struct key is more informative than an array index, I would use structs. Then you could use something like StructFind or StructKeyExists in order to check existing keys...
