10 years ago, I would have taken AK over JJ because of my own experiences when playing Jacks. But, I've come to realize that over time, JJ is the more profitable hand than AK, but I try and think of it completely different. To me, it's about maximizing your win rate with each hand so that when you are dealt each hand in its own situation, you can play them accordingly.
So for me, I like each hand equally in any situation.
