Well,a few months ago I started the discussion of what's the best and worst Ace Attorney Case. Well, another topic regarding that matter would be cool,but now let's do something different!!
The rival from the crossover with Professor Layton won't be included. Also,two rivals from Investigations 2 will be,well technically there were two,if one wasn't that smart is another story.
My favourite rival gotta be Klavier Gavin.He was the first rival that wasn't a jerk to the defense attorney and actually helped you uncovering the truth,rather than just trying to incriminate the defendant. Well he certainly lacked character development,despite having the biggest potential in the franchise(We all know AJ:AA was rushed).
I'd rank the rivals like this;
Klavier > Edgeworth > Blackquill > Debeste > Lang > Godot > Franziska > Courtney
Don't get me wrong, I like the concept of women being the main rival on Ace Attorney games,I just can't stand a person that freaking whips everyone in court and I think that Justine was quite a pain to deal with,because most of the times her arguments were too strong and it was frustranting to deal with her. Also,I never played SoJ and DGS,so that's why Nahyuta and Van Zieks are excluded from this list.
