What counts as smite do minecraft?

numbers if it helps: smite V adds 12.5 damage against undead, sharpness V adds 3 against everything (java). so on a zombie smite wins by miles, on a creeper it's worth zero. java also lets you put smite on an axe if you'd rather keep sharpness on the sword.

smite only does anything against undead - zombies, skeletons, husks, drowned, wither skeletons, phantoms, the wither itself. on anything else it is a completely dead enchantment. it also doesn't stack with sharpness, you get one or the other on a sword, so smite is only worth the slot if you're specifically building for a mob farm or nether fortress runs. the ender dragon isn't undead, which trips a lot of people up.
