If you gear a 1400 kv motor and a 1700 kv motor for the same speed, the 1700 kv motor will accelerate faster because it will draw more current and therefore more power. It may also heat up a little more, but the lower resistance keeps that from happening so much.

From my experience, my Neu-Castle 2650 on 4s geared 14/46 is about the same top speed as my Tekin T8 1900 kv motor geared 20/46. The 2650 accelerates fairly hard, and the 1900 is pretty sluggish, but the 1900 runs a good 15-20 degrees cooler. The 1900 on 6s geared 14/46 blows the 2650 on 4s out of the water in speed, acceleration and temps.
