I use a serger to make quilt tops that I am going to use a duaval (cover ) for my down conforter. It stops the fraid seams and I can have a quilt top for the comforter. I use mine year round here in west texas. Use to put it away during the summer in Galveston but this weather here is crazy.
I also use the serger to do summer clothers for my grand daughters. Most of the sewing goes real quick on a serger. I have a Rex Overlock and I love it. It is easy to load too.
