Quick Answer: Get the backpack if you want one bag that does everything, hands-free, from newborn through the toddler years. Get the duffel if you want a lighter, grab-and-go bag for quick trips and shorter outings. That is the short answer. If you are still deciding, here is how the two actually compare when you are the one carrying it every day.
Why this comes down to how you carry, not what you carry
Both bags hold the same essentials: bottles, wipes, snacks, a change of clothes, your own stuff. Both are neoprene, both wipe clean, both come with extras. The real difference is how you prefer to carry bags.
A backpack rides on both shoulders and keeps your hands free. The weight is distributed evenly to both sides. A duffel carries on one shoulder or in your hand and is faster to grab and go.

The backpack: the everyday workhorse
The backpack spreads weight across both shoulders, which matters more than you would expect once it is loaded. The backpack keeps your hands free for everything else you are juggling.
Maria F. put it plainly after a family trip to an amusement park:
"I can have the bag filled to the brim and carry it on my back all day with no worries... as an overpacker, I only had to bring 1 diaper bag instead of a diaper bag, medium cooler and a tote bag."
That is the backpack's whole case: one bag, packed heavy, carried comfortably, hands free.

The duffel: the grab-and-go bag
The duffel leans into speed and simplicity. It is lighter to reach for, easy to keep by the front door, and quick to grab when you do not want to haul the full setup. For quick trips, it is often the one parents actually reach for.
Just Jessica keeps hers ready to go:
"This is the perfect size for a quick trip, when you don't want to haul the whole diaper bag. I always have it by my front door ready to go."
And Anjelica sums up the lightweight, grab-and-go feel:
"Super lightweight and durable... Easy to grab and go. You can fit a lot of stuff into it too."
The trade-off: a loaded duffel sits on one shoulder, so it suits shorter outings better than all-day travel with a newborn. Though we have seen a few people wearing it cross body, which helps distribute the weight (and makes it look less like a diaper bag).

Our recommendation for first-time parents?
If this is your first bag and you are choosing one to cover the most ground, start with the backpack. A newborn means more gear and longer days, and the hands-free carry is the thing you will be grateful for on the hard days.

Reach for the duffel when your outings are shorter, your load is lighter, or you want a second bag by the door for quick runs. Plenty of parents end up wanting both, one to carry it all and one to grab and go, but if you are picking one to start, the backpack is the safer first bag.
Both come in colors that suit moms and dads (Black, Slate Blue, Grey, Mauve, Cream, Olive), so either one works whoever is carrying it.
