Clearly multiple models under the same name: I guess the 8 just means 8 speed hub gears.

Probably both have back pedal brakes which I hate; can't get pedals into the right position to start up (Dutch and Danes seem to scoot to start), brakes engage when I absent mindedly back pedal when going along a nice slightly downhill bit.
Probably good if you are used to them.

Lots of manufactures of bikes (and many other things) give almost the same name with maybe minor qualification to very different goods, but different names to trivial variants of the same thing.
