Sorry to be a non winchesternhead, but Marlins were made to scope with the side eject and I have been told much stronger.
From my research the Winchester is considerably stronger than a Marlin 336. While both are strong enough for normal and even heavy use, many 336 have come apart. Some Wincher 94's have also don't get wrong but P.O. Ackley had one that had a double load of fast burning pistol powder. The barrel literally detonated as well as the entire front half of the gun. The receiver received no damage except the threads where the barrel was ripped out. The action was rebarreled and the gun put back into service. The Marlins do have the advantage of easy scope installation. I have both makes and enjoy both so don't have any axe to grind.
