It is comfortable. I've restrung it several times to get it right.. The important thing is that the lower strands are longer than the higher strands, so the necklace curves in a U shape when laid on a flat surface. If all strands are the same length, the top strands will sag when the necklace is worn, or it will be uncomfortable.
Getting 3 strands to nest just right is definitely tricky. I still have one lower strand that is a hair longer than the others, and it has to be the size of the pearls on that strand because every time I restring it, it's always just a hair longer than the others.
