the 5800 brushless I found at least was more like a 14 turn motor, with a well turned 19turn able to be very competitive against it.
The advantage of the 5800 brushless is the maintenance or lack there of you have to do as well as the torque it puts out. Also longer runtimes are a plus.
If you are looking for all out speed, look into a GTB, I would do the 6.5 version but if you really just want speed, the 5.5 will be your choice.
