I love Hobbs 80/20 fusible batt. Con: having a large enough spot to iron it on. I use the old carpet in my basement. I assemble the sandwich on the floor, iron the top from the middle out, flip the whole sandwich and iron the back in the same manner. Con: it isn't a puffy quilt although the batt does puff a bit after the quilt is washed. I am always careful to not use steam to iron in case it dissolves the water soluble fusible. I don't know if it would but I err on the side of caution.
