The Mover Pack is an affordable duffel with simple backpack straps, solid materials and a few solid pockets for organization.
They’re actually surprisingly comfortable. I, personally, like to travel with a travel backpack due to their robust straps, optional hip straps, etc.
But as far as an affordable duffel with backpack straps goes, this thing is solid. (And bonus for it not looking like a big, sticky, rubber patagonia or north face bag.)
The material and zips and organization all feel surprisingly solid.

The Aeronaut from Tom Bihn is an excellent duffel/backpack conversion bag with minimal organization and insanely durable materials and construction.
The Headway MLC (Maximum Legal Carry-on) from Patagonia is a very functional gear bag that works better as a duffel due to it's uncomfortable (but hideable!) backpack straps.
The Travel Bag from Peak Designs is an extremely well designed, quality bag for modern carry-on adventure and business travel.
A very well designed, stylish travel bag for one-bag travel with enough pockets, organization and access to make travel smooth.
