Defensive attributes are much more important for ball winning midfielders (tackling, covering, heading). Deep lying playmakers and advanced playmakers both need flair, creativity, passing and technique attributes. If your player has these attributes, consider him for a playmaker position. Then, if he also has good tackling / covering / heading he could be played deep lying, if he has got finishing or distance shooting abilities he could be an advanced playmaker.
Personally, I rather decide based on the special moves they have. Like if someone has powerful / targetted shots, deadly passes, or running into open areas they will play in advanced position while someone who is looking for challenges or has close covering they will play deep lying position.
