I'll start off by saying that Misty was my favorite, and this could quite possibly be due to nostalgia goggles. I know a lot of people really hate it when people say things like, "First season was best!" and "Misty was the greatest companion!", and I understand why. It's silly to think that the show hasn't improved since the first season. In terms of plot, art, characters, pretty much everything, the show has taken great leaps. Still, I like the beginning best due to the classic anime feel. I like the hand drawn imperfections, I like the classic anime stereotypes. Heaven help me, I love Misty as a classic tsundere.
Putting my nostalgia aside, May, Dawn, and
Iris are better characters, simply because the writers took their time with them. I feel like the biggest reason Misty didn't get as much screentime was because of how geared towards boys the show was at the beginning. As the creators discovered they had a fairly large female fanbase, they gave her a larger role.
