I've watched both since rookie ball.  If you're just using scouting reports to make a point...then you'll miss the real trajectory of a player.  I've given Waters props for his improvement to date, but 'loud' contact is not a barometer for what makes a prospect good. He's always made loud contact...WHEN he's made contact.  37% SO is disastrous no?
I'm stuck on far superior and those same scouting reports have always put Pache ahead.  Even a failed mlb stint has Pache ahead of mid season rankings.  I really don't care about those as much as I do when I see them play.  I used to put their reports here but Meh, I'll let others draw their conclusions.  Pache may never hit.  I am less enthused about him reaching decent Ender level and still....I'm as high on him as i am Waters.  Which doesn't mean anything I guess.
