I really think that unless you just don't like them, then save them and finish them as you can. Learn to either stitch in the ditch, or trade service with a long armer in trade quilt tops = quilting.
But I wouldn't be in a hurry to do anything with them at all. Then, as many do, you can choose one and finish it as you wish--and as you have money. Do you feel like you have to keep the pile down to "0" or below 10? I don't think you have to.
