Why do people choose Will-O-Wisp over Toxic sometimes competitively?

Toxic badly poisons the target, which means it will keep increasing the damage dealt, unlike Will-O-Wisp, and Toxic has higher accuracy. So why do people choose Will-O-Wisp instead of Toxic sometimes, when the Pokemon can learn both?

I frequently use both, but I use WoW over than Toxic for some reasons.

I like running a set with EVs in HP and Sp.Defense and WoW.One of the bests pokémons for this works isGiratina; it has high HP and defence stats, good RestTalk user with WoW or Toxic.

Giratina @LeftoversCareful NatureEVs - 252 HP / 200 Sp.Def / 56 Def- Will-o-Wisp- Rest- Sleep Talk- Dragon Tail

Hope this helps.

Because Burn halves the opponent’s attack, and burn can affected both poison and steel types, something which toxic is not capable of doing.

Basically, burn cripples any physical attacker (there are exceptions like Guts Conkeldurr). Additionally, will-o-wisp is only learned by a select few Pokemon, mostly ghost and fire types, while practically everything has toxic, so if you’re Pokemon is one of the few that gets will-o-wisp, you might as well take advantage of it.
