The AW hub gear ratios are 3/4, 1/1, and 4/3 (rear wheel revolutions / crank revolution). They are way too far apart for my tastes -- shifting a 3-speed hub is exactly shifting between a 39 and a 52 tooth chainring, with no option to find an in-between ratio by shifting the rear derailleur.
My favorite 3-speed setup by far was my 12-speed hybrid, which comprised a 14-16-18-20 cogset on an AW hub, with a 40T chainring. With 26" wheels, I had pretty decent ratiometric progression from 40 to 100 gear-inches. Since the 3-speed ranges almost overlapped, I tended to use low gear with the 20, 18, and 16-tooth cogs, second gear with all four cogs, and high gear with the 18, 16, and 14-tooth cogs, giving me 10 great ratios, 40 percent of which were in the most efficient direct drive gear.
