Depends on how you have it geared and how you drive. If the two systems are geared the same the slower motor will give you longer runtimes if you spend most of your time at top speed. If you are constantly accelerating the 1515 may be able to pull more amperage (accelerate harder) and your runtime could be lower.

Geared for the same speed I would say the 1515 will have less runtime, as you will probably be pulling the trigger enough to use the extra power.
