Should I get a boot backpack or a duffel-style boot bag?

It depends on your transport needs. Boot backpacks are better if you have a long walk from parking to lodge, need your hands free to carry skis or hold children's hands, or navigate icy surfaces where carrying a duffel is awkward. Duffel-style bags are better if you primarily need airport transport, want a simple inexpensive option, or prefer a bag that can double as a boot bench for changing. For daily resort skiing, the backpack style is usually more practical.
