Re: Best characters in each class, plz share opinion!
I'll join in, too. There are several character classes that I hardly play (yet) and I will note those. Many of these choices are difficult as I often have more than one favorite with classes I play frequently. I'm only a medium skilled player, and many of my choices reflect how forgiving the characters are with my abilities, how effective I can be with them. But others are because of how fun I find the variant to be to play.
Also, for many months I was one of those players who only liked to play plants. I only took to zombies when the Spooky Squash boss hunt occurred. Since then, I've developed a lot more skill with some of them, but I still lag behind compared with plants. With the exception of the Sunflower class, at which I'm very good, I suspect you can see a thread running through my choices of how forgiving the character is to poor accuracy.
Often my choice of character will vary a lot depending on whether I'm playing ops or multiplayer.
PLANTS
Peashooter: Electro Pea, but I will only use him in multiplayer if my team is getting trashed. I like all the splash variants, perhaps toxic is favorite.
Sunflower: I've mastered all but two (Metal Petal and Mystic Flower). Vampire Flower is by far my main, but Alien Flower is really fun.
Cactus: Default Cactus. I suck at playing cactus.
Chomper: This is another class I don't play much. Disco Chomper is the most fun but I'm hoping to get skilled at Hot Rod along the way.
Citron: IRON CITRON! i also love playing Toxic Citron, heck they're all fun and effective.
Corn: Commando Corn, followed by Default Corn
Rose: Default Rose
ZOMBIES
Imp: S.H.R.I.M.P. Scallywag Imp is super fun but not so effective for me.
Soldier: A class I haven't done much with. I use Default or Scuba, and will get around to playing the soldier class more soon.
Engineer: Another class I haven't developed much. Roadie Z is my favorite.
All-Star: The first zombie class I got used to. I've only worked through a few variants. I do best with Cricket Star, but I'm levelling up Goalie Star right now, and he's getting pretty darned effective with the ice upgrade.
Super Hero: Toxic Brainz. I don't really care for playing this class but Toxic is the most fun and effective for me.
Pirate: I've barely played him at all, no preference worth noting.
Scientist: Computer Scientist. Before I got him, Chemist was my go-to. Computer Scientist seems like a direct upgrade from Chemist to me, with a bit more range thrown in.
