Is a hanging toiletry bag actually worth it over a flat Dopp kit?

Specialist travel subreddits like r/HerOneBag and r/onebag strongly favor hanging designs for hotel and hostel travel, where counter space is unreliable. A flat Dopp kit is lighter and easier to stash, but reviewers consistently say once you've used a hanging bag with a sturdy hook, it's hard to go back. Hybrid bags that do both exist and are often the safest pick.
