The first point is true for a SA 8 hub. Which is ideal for a small wheeled bike as 1 st is direct and the rest geared up afaicr.

Shimano 8 speed is upgeared from about 5.

Secound point is correct if you have a nexus 8 direct drive is about 5. Aa reasonable cruising gear. Dual drive hubs (cassette and 3 speed ihg) mean that you can use 9 speeds in direct drive.
