I usually use gears 8-14 (flat all around). The really nice thing is that you have lots of lower gears to choose from when you need them. Gear ratio ranges from 1.4 (1st gear) to 8.9 (18th gear). Steps between gears are quite small, so I usually shift up or down 2 or 3 gears at once. When in hilly or mountainous regions it is nice to have the small steps. Shifting is a no-brainer with crisp indexing.
Best thing about it is almost zero maintenance.
Only thing is the twist grip, which can be slippy when wet.
Yes, it's expensive but it's my commuter so I save on the car/gas/tax. Company guarantees 60.000km but that should be very conservative. The gearwheels are produced on car manufacturer's production lines (filling idling times) with very high quality standards. iirc Rohloff started with a 60.000km guarantee as well, but there are lots of hubs that have done much more than 100.000km.
Some argue you save on chainwheels/chains and cassettes. Maybe, I never did the math. I just thought it is a nice piece of engineering and I do like stuff that works.
