With laminate it usually comes down to what you like best,I usually ask my customers what they want ,makes them feel important and it is their home.Yes sometimes it is easier one way or another,veiw points from one person to another differ always,sunlight shining on it ,a big long run looks like a bowling alley to some to others it makes their house bigger .My motto is whatever makes the customer happy,unless it is hardwood ,the manufacture recomends crossing floor joists,or they void your warranty.Or unless somebody else will assume responsibility.
