A tracker is only an externalization for the memorizing skill. As regard gaming ethics, this is considered cheating (for instance online poker sites are banning users of such applications).
Any CG is having some rewards in the end, even if only of virtual nature. Take Gwent. To reach them season or rank rewards, one has to play a lots of games while the attributes defining the mood, and implicitly memorizing, are changing based on surrounding environment and based on biorhythm. Sometimes is easy to keep track some times there is lot of distraction. Is like in sports, good days, bad days. But this is part of any competition.
A player whom uses a tracker will better avoid the negative influence given by these bad days when memorizing skill is not running at full capacity.
My conclusion: on long term they will be advantaged. So OP is right, console users are disadvantaged in comparison with PC users.
