Better than Brock how?
No offense to any Misty lovers here, but Brock is ten times better than Misty. He might not get enough screen time, but he's extremely knowledgeable when it comes to certain things and he cooks! He's like Ash's personal PokeMart and PokeCenter and Love Specialist, but Ash is about as dense as a doorknob, so things like love and crushes go straight over his head. It's just Pokemon this, Pikachu that, and Team Rocket blah blah blah.
So he cooks. Big whoop. Ash and Misty already handled both Viridian forest and the Orange Islands without his help and were fine (Heck, the former was before they even met.), plus he never even cooked when it was extremely vital that he did need to or make necessary preparations (like in "Pokemon Shipwreck"). And, love specialist? Doubt it. He basically jumped on any woman he found. It's already bad enough that we have Glenn Quagmire, Charlie Harper, Master Roshi, Krillin, Brody Mitchum, and the like in terms of that stereotype of heterosexual males that we're expected to act exactly like, and Brock's only making it worse. If his cooking was TRULY that important, then you can basically say that Ash and Misty died in Viridian Forest or Orange Islands due to his absence.
All Misty really did was hang around and freeload, she did nothing to contribute to the group. Ash had his battling thing and Brock was a Breeder. Sure, she had her once in a blue moon captures and once in a blue moon battles, but that was really it, she didn't do anything else, oh wait, that's right! She one that one contest or something or other and took care of a Togepi for 3 generations. But the writers wrote it off by having it evolve into a Togetic she couldn't keep, because it was
'The Chosen One.'
Actually, I have a huge list of how Misty did far more than just "hang around or freeload," since, even IF you weren't bashing Misty, that was still a very inaccurate statement. I suggest you prepare a huge meal and rest your eyes, since this is going to be very long:
She saved Ash in Episode 1, she was the person who came up with the idea of how to escape from the St. Anne, she was responsible for winning that money to fix Moe's port in Beauty and the Beach, she saved Porta Vista from the Tentacool/Tentacruel, she was the one who took care of that Gastly, she was the one who stopped JJM from invading the Fuschia gym, she was also the one who stopped the Backpack thief, she got Mikey to try and tell his brothers that he is to stick with Eevee, she was also the one who got Melvin off of his feet, she helped Jigglypuff regain its voice, she played a pretty vital role in regards to saving Ash from Aerodactyl (she was the one who suggested that Jigglypuff sing its song), she also won that Princess competition, she was the first person to find out that the Meowth was a fake, she stopped B&C's breeding scam and got Ash and co. out of Jail, she was the primary reason why Ash was able to battle Blaine (had it not been for her capability to solve riddles, I'll bet that Ash would not have faced him), she saved her sister's show from Team Rocket, she saved Ash and Brock during the first movie, she saved Ash during the second movie, she held off Molly for the third movie, she cured Ash, Tracey, and even Jessie from the stun spore fever, she had the Whirl Cup, she did that race, she was the primary reason behind Ash teaching at Violet school, as well as Ash getting back the GS ball, she was the primary reason why the Sunflora festival continued, she fought against Dorian (making her the first character other than Ash to challenge a Gym Leader, period), she saved that Marill, she tried to get Brock to go with Temaku, fought for Totodile, and a lot of things that I can't think of at the top of my head for the moment.
This is not tended to bash Misty, because I like her, but I'm just saying IMO, that Brock should stay, his Pokemon might be non-existent to the cameras, but I'd prefer him over Misty and maybe or eventually, they'll flesh out his status as a Breeder.
If they wanted to flesh out his status of being a breeder, they should have done it way back in Johto where they DID have breeding. Besides, I don't want a character who would end up being a bad influence to kids (his running gag, for example, is just in bad taste, and I've already stated why.).
