I mostly use batiks when quilting and I am just now getting to the point of using other fabrics. I love batiks. I pre-wash with colour catchers and don't sweat the right or wrong side that much. If I can't tell when I am sewing with them, I doubt others will when looking at the finished quilt. I have found that using all batiks produces a heavier quilt than regular fabric. I guess that is because of the tightness of the weave. But as I say, batiks are my go-to fabric.
