One of the first quilts that I ever made had fleece for batting.I didn't know any better. I saw it 5 years after I made it, and it looked like new. It was a baby quilt and it was washed a lot. My son loves fleece so I used a king sized fleece blanket for the backing of a Scrappy Trip Round the World. Also used a furry fleece for the back of a Metro Rings quilt by request. The recipient says it's super warm and loves the 'silkiness' . I don't think that the fleeces are really much different from minky- like fabrics. Some may stretch more than others. I think fleece is really easy to work with- just make sure you use a non-pilling one.
