Say your going on a trip, hiking/backpacking/or just packing to be prepared, how do you typically pack your clothing?

I see some will pack all the different types in one package/stuff sack/whatever so you have all your underclothing together, outer pants/shirt in one, etc

Others pack a bundle of one set of under/inner clothing and one set of outer clothing in each pack/sack for each planned day. So a two day trip will have two stuff sacks, one for each day.

As I start to prepare to swap summer gear and winter gear soon I wonder if one method might be a little more efficient than another?

Thanks
