I don’t have a clear enough idea of the way I myself think about counterfactuals to compare. Pearl’s counterfactuals are philosophically unenlightening, they stop at explicit definitions, and I still haven’t systematically read Drescher’s book, only select passages.
The idea I use is that any counterfactual/event is a logically defined set (of possible worlds), equipped with necessary structures that allow reasoning about it or its subevents. The definition implies certain properties, such as its expected utility, the outcome, in a logically non-transparent way, and we can use these definitions to reason about dependence of outcome (expected utility, probability, etc.) on action-definition, query-replies, etc., through ambient control.
