What is the most overpowered item in Fortnite?

Can you tell me what the most overpowered item in the popular game Fortnite is? I've heard rumors about certain weapons or items that seem to give players an unfair advantage over their opponents. Is there one specific item that stands out as being overly powerful, or are there several that are considered to be at the top of the list? It would be interesting to know which ones the community considers to be the most imbalanced and what effects they have on gameplay.
