Hi, what type of venue?
Both work in winter and both need to be worked slowly and I mean slowly.
Drop shot will be most effective as can be slowly drawn along bottom and twitched.
I ask about venue as dropshot cannot be cast very far. In this case use lightest jig head possible for distance and depth. Cast and let it hit bottom, leave it for 30 seconds up to 5 mins then twitch it and let it sit again etc etc.
One cast can last twenty minutes or so.
Then theres lure size - Oddly bigger sizes can work better in winter.
Energy verses effort is how I see it from a predators point of view.
