Staying with the same family of motors, the torque would be near the same. Just power band moves a bit.
I like the boost option as it gives me more things to play with, instead of getting bored with one setup. Going with the lower kv motor, makes it easier to drive at lower speeds and have the boost kick in at for speed. The higher kv motor will use more power and not so much fun to bash with other that zooming up and down.
