I use it and find it warm and cuddely without being too bulky. It handles well in the machine and can be hand-quilted.
It allows for greater distance in quilting lines but I always quilt more than the bare minimum.
Some of my quilts start with prewashed fabric - some with unwashed fabric. I cannot really tell the difference once the quilt is washed. However, I love the look of the quilt after it is washed and a little puckered.
Only experience will tell you if YOU like it or not.
