With acrylics, neither. The paint is on your brush and is thin, with good flow properties. Strokes are short and fast, all in the same direction (where you want the colour to be stronger), very little pressure at the start, perhaps more at the end.
This gives a faint line at the start of the stroke and a bit stronger at the end. Very little paint goes down (practice brush control so you can use a larger brush holding more paint). The process is repeated (layering) with strokes spaced across the surface to give a line texture, and moving closer to the stroke direction.
With oils, the and spread properties do allow you to work with a dry brush (or feather, which is where the effect got its name) on previously applied oils. However traditionally this is done in the reverse method (pulling back paint you don't want in a certain place), using stronger pressure at the start of the stroke to pull more oil, then reducing pressure to move less. This isn't really possible with acrylics due to the very fast dry time.
