Which item do you use most?

I think med kits are probably the strongest (except for keys) item. They will be useful against any killer except plague.

Flashlights are situational and often rely on the killer making misplays

Maps are only good for dealing with totems or playing against a hag/trapper

Keys are super strong but they're pretty rare, compared to a med kit where you can just take a brown every game and get good use out of it.

Firecrackers are valuable because of their rarity so I rarely use them.

Toolboxes are decent but the toolbox rework made them way more situational and save way less time so I think the med kit is typically more useful/versatile now, definitely would have been toolbox before the rework though, couldn't beat faster gen speeds sometimes for the whole game with the right box.
