Is not easy to answer as they're not equivalent and can't be measured against each other.

No way to answer that. Depends on too many factors including but not limited to row count and indexes.
Question doesn't even make sense, IN and AND are not in the same class, one is part of a predicate, one is a logical operator that combines two predicates
