So, this is basically Dawn vs May, only in terms of their skills as coordinators. I've seen people say May is better simply because she's been entering contests longer and stuff, but I disagree. Yes, she has been in more contests and has some powerful Pokemon (namely Blaziken, Venusaur, and Glaceon), but that doesn't automatically mean she's better.
I honestly think Dawn is the stronger coordinator. Just look at the facts.
- Dawn's mom was a top coordinator and Dawn herself has watched her perform before. Thus, this made her want to do the same, so she already had knowledge of contests when she began. This gave her a head start. May didn't know contests even existed when she first started out.
- Dawn reached the Grand Festival finals, if I remember right. May didn't.
- Dawn also defeated May in the Wallace Cup. It was by a small margin, yes, but Dawn still came out on top.
- Dawn ALSO managed to defeat the same coordinator who ended her mom's winning streak. May never accomplished a victory of equal calibur.
This is just down to opinion, but I also think Dawn had much better move combinations. I mean seriously. Ice Chandelier? Flame Ice? Ice Aqua Jet (before she traded Buizel to Ash)? And especially all of those cool things Dawn did with Buneary's Ice Beam. That was truly spectacular. Dawn is also the brains behind that spin technique that evolved into the impressive Counter Shield. She also has some tough battlers, like Mamoswine and Togekiss. Ambipom as well, before she left it with that ping-pong guy.
And that's what I think. Who do you think is better?
