I love the SILK floss a lot! I accidentally bought the bamboo one from the same company and immediately felt the difference. The silk floss is smoother, flatter, and therefore has more of a surface against your tooth. It is like gliding a ribbon over the sides of your teeth. It doesn’t get caught. Nor does it fray. I cannot say the same good things for the bamboo version. But each person’s teeth sit differently, so some might like the thin thread of the bamboo one. I didn’t like it. The bamboo frayed and ripped apart or snagged on my teeth.

It's been a cool thing to try, I have found it slightly less durable than my previous floss from other companies. But it's not a huge difference. It could also be user error.
