I have found it depends on the actual stitch design you are using. You have better luck using a very open design and one that does not go backwards very much. If the design is too heavy or too dense, the stitches will pile up on top of each other and make a real mess of things. I use a scrap of left over fabric from the quilt with batting to test some stitches out on. I also use the IDT because of the layers needing to stay together. I hope that helps. Just keep testing stitches. You will find some work better than others when using the for quilting. I also use 505 spray to stitch the layers together. They don't slip that way.
