thicker works best for holding lines longer, thinner works best when you need to kill things faster. Most of the time you'll only want to really stretch your ranks thinly, if your up against archer/crossbow fire (a thin line works even better then a loose formation at times), or to help cover a larger area more easily (like with pikes near your archer units). For the most part, you'll want a middle way anyways, since if its thin you get attacked by more then one unit or being charged by cavalry, and with thick lines you end up having yourself getting flanked or easily hit by ranged weapons fire (i've lost upwards of 60 men to a single trebuchet round because my unit was too tight).
