For my Brother 1500S, the 1/4” foot is for all the sewing. For FMQ there are 2 feet. The one with the machine has great visibility. Since it’s not round, a Judi foot is used for echo quilting.
For Bernina 770 with 9mm, the quarter inch foot is difficult for me to be accurate. I use the clear foot and move the needle right 2-3 clicks. This gives the fabric plenty of feed dog coverage for better fabric movement.
