I usually use steam a seam lite.. I also have used a lot of wonderunder.. I like both products. I have not liked heat and bond that well.. When I use them on a quilt I don't like that stuck down look or feeling, so I cut out the shape, and then cut it again to take out the most of the inside leaving only a quarter inch or less.. I iron that to my applique, cut it to shape, and pull off the small slip of paper left and apply the applique to my piece.. Since I always stitch down my appliques in one fashion or another the bit of fusible left on the fabric disappears under the stitching and the piece feels like it was just stitched on.
