Which Ace Attourney Game Should I Get

I recently played My friends AceAttorney game and loved it but I can only afford on of the games and would like to ask which of the 3 are the best.

I Don't Care about which is the most original.

If 3 is better than 1 but has no new features than I would like 3 better. thanks

Get 1 first and then get them in order...

There is about one case in each game that continues into the third game. It's not completely necessary to get them in order, but it would be best to.

thanks for that.
