I've never had an issue with palm rejection, and overall, I love the Macbook trackpad. The only issue I've had is that during the years I used a mid-2012 MBP, I developed a habit of resting the tips of my fingers just below the spacebar. For years there was just enough space there to make that possible. Now there isn't, and I still get the occasional issue when my fingers go back to that spot out of habit.
