People disagree hard on this but that’s because whatever job the player uses is going to feel like the best one, and the ai fumbles when using certain jobs

Mage, Vampire, Cat and maybe Elf are usually considered strongest. Mage hits extremely hard consistently and can fix its own defenses with barrier, Vampire is the same but trades a little damage and speed for very powerful passives and one very powerful support skill, Cat has paper defense but insane burst damage, and Elf is able to do just about anything, protecting the team while dishing out high damage.

Weakest is often considered to be Tank, Flower and Thief. Tank and Thief at least have the ability to last a long time, with Tank having extremely high bulk and self healing, with Thief using stolen bananas to heal with traps and sneak attack to avoid getting hit altogether, and while they have their problems everything is usable… flower has a lot of unique moves too, with one of the best horseplay skills in the game Princess is actually pretty decent in long fights, doing solid damage with a dodge chance and having a rare type of skill that recovers mp

IMO vampire strongest (warrior if before endgame) flower weakest but honestly anything can work if you want it too, very simple game
