I would akin to Light having the lead at this point of the anime, even if his lead which was originally so far ahead was cut short by his own egoistic attempt of self-recognition and rejection of negativity.
The main point lies in the concept that Light has full workings of how the Death Note works and he knows his own weapons and capabilities to see himself what he can do at a particular moment and what he cannot do, (( Someone else may assume an empty-handed Light is capable of just killing a criminal with the face and name, even when in reality he can't because the Death Note or a pen isn't in his hand )), while L only has little ground to work upon and half of his hypothesis statements regarding how Kira kills and the limitations behind the murder patterns would be limited to mere 'what ifs'.
