In my opinion the ones who are active should have the advantage over the ones who are not..
They already have a lot of advantages, especially in the transfer list.
Changing to active game management will involve an extra 4 hours per week at the specific time of the game. If I have to make a choice between doing that or losing the game, I would have to quit.
Of course, if the coaching is so good that the AI is better than me (or you), I wouldn't mind.
