Both of the methods are good for raising awareness and to get the "this is a dream" realization into your regular dreams, as realdealmagic points out.

If you manage each type of your practice few times a day, that's good.

All day awareness is not really something you do. It's more of a lifestyle. When you are always aware of your surroundings. Like a little mouse, that comes out of his hiding place has to be aware of everything - sounds, smells, movement, changes in shadows, now items on the ground... unles he want's to become lunch.
