I have Randonneur, WTB dirt drop, and Salsa Woodchipper bar. From my experience, the randonneur is great for long road travelling maybe light offroad too, the woodchipper is great for offroading but not so good for long road touring. The WTB is the best of the world, good for offroading (when in drops) and good for long road travelling (multiple hand positions) although it feels a bit wider for me (in the drops) and the weight is heavier than others.
