Marla, freezer paper is easier for some types of applique.
I use the basting method for those tiny pieces, appliques that include seams to turn under, and odd shapes. It's easy for take along projects, too because you don't have to worry about the adhesive of the freezer paper.
If I'm working on them from home, I can whip up some freezer paper applique quickly so I still use that method from time to time.
