Are compression packing cubes actually worth it over standard cubes?

The consensus across r/onebag and r/HerOneBag threads is that compression cubes meaningfully shrink soft items like t-shirts and underwear, but they don't compress dense items (jeans, sweaters) much beyond what rolling already achieves. Multiple community threads note compression also creates dense, brick-like shapes that can be harder to pack around. They're most useful for carry-on-only travelers trying to squeeze a few extra days of clothes into a fixed-size bag.
