I prefer flat bars and bar-ends on any bike that travels off-road, in bad weather or for a long time. I can use drops but they don't do well in bad weather or off-road, and bar-ends give varying hand positions. Plus I can just flip the bar-ends to be a bit more aerodynamic. Still, I would say it depends on your usage of the bike, the terrain/weather you'll ride in, and your own adaptability.
