I will give my money to the loyalist. Space marines seem to be able to keep it together a little better than chaos space marines in general. Even in close combat. But its close definitely and a big generalization can't be made.In the Legion of the Damned novel the Excoriators do pretty well despite being outnumbered and dealing with Khornate marines (close combat beasts).

If the loyalist officer is from a very strong chapter like the Ultramarines, Iron Hands, Dark Angels, (officers from these chapters have taken out Grater Deamons and Avatars let alone CSM) and the the traitor is from just from some warband than loyalist more likely. But if the traitor is from a top notch war band, especially sporting some sorcerous/favortism like we have seen with some officers in the Death Guard, Thousnad S, Word B, B Legion, and the marine is just your regular Guilliman/Dorn adorer than maybe the heretic.
