I have been quilting since 1966-67. I have tried many times to make a perfect quilt. After making hundreds I still have not made a perfect quilt. Just a little competition with myself. If a seam doesn't line up after three tries then it stays.
If I like my finished quilts then that is all that matters. I do mostly FMQ, I love it and love doing it. I donate most all quilts to foster kids in our county. I make them to be warm and use pretty colors. I would never enter a quilt into competition. Just not my bag.
