The first one. I dislike any and all Snail's Trails and both it and the log cabin are too repetitive for my taste.
When it comes to quilt preferences, if you ask 10 different people, you'll probably get 10 different responses, according to each one's personal taste. That's one of the many things that is so great about quilting.
Oops, I missed #4 and the adjusted #1. Still like #1 better.
