Ask a hundred people and you get a hundred answers.
I own both....I have a Henry Frontier which is fantastic (but then again I like lever actions) and I have a 982vs Marlin bolt action. Both brands are fantastic. Henry is known for its lever action guns and they are smooth as butter. Marlin is known for its accuracy and on their stainless steel models the action is smooth as well. Bolt or lever...you choose....its what makes you happy. If you went with either you would have made a great decision and both are much more accurate and reliable then the person holding them.
There is no "hands down" winner....both manufactuers have a great history of making quality firearms. The rest is pure opinion and sentimental memories.
