Titan jumps go high or far, but quickly taper out. They let you get that short-term burst of momentum, making them arguably the best for sheer height or momentum gains in an acceptable period of time. Warlock jumps are "weaker", more drawn-out versions of the Titan jumps. It's very rare that you actually need flight [i]distance[/i] instead of height or speed. I'd have to say Warlock jumps are my least favourite for this reason. Hunter jumps are simplistic and efficient; you press the jump button, you move instantly and start to fall just as fast. No sustainability, immediate results. That's why they're my favourite. I just find the simplicity more reliable.
