Hi Rosasharon, Welcome to the QB. You will get lots of varying opinions on batting, like fabric and thread it all boils down to what function you want and personal preference.
You probably should try expanding your purchase point to something other than JoAnn as they are really only a fair price point if you have a coupon or they are having a 50% off sale on it and their selection is limited. I have seen the same W&N (warm and natural cotton) priced regular for almost half of what JAF charges at quiltshops because JAF adjusts the price for coupons.
Here is a good link to a blogger that did a great comparison chart for batting
