Is a rolling underseat bag worth it over a tote or duffle?

Reviewers across r/onebag and r/HerOneBag consistently note that rolling underseaters add 2–4 pounds of empty weight and lose interior volume to the wheel housings and telescoping handle. For frequent flyers with back or shoulder issues, that tradeoff is worth it; for lighter packers or short trips, a soft tote like the Travelpro Maxlite 5 or a Narwey-style duffle is lighter and packs more clothing per liter.
