In general, Internal-gear hubs are much more durable than derailer systems. The Rohloff has a reputation for being bulletproof. My NuVinci has been trouble-free for 5000 miles, including a 3200 mile tour.
Personally, I'd never go back to a derailer system unless I was racing and had a support crew.
