Pretty much -- cars are getting heavier and heavier, so more torque is necessary to keep pushing 'em to higher and higher speeds and acceleration.
While slotless motors rev faster, have less inductance (so respond faster) 4 pole motors have much more torque -- and with some of the software changes we've made to run the big 4 pole motors well (like the 1515) the differences between the motor designs have become smaller.
Note that I was talking about "light" 1/10th scale vehicles in that post -- but the trend recently have been to heavier, more robust 1/10th scale cars.
Also -- please note that we haven't discontinued the CM36 motors -- they will still be available. So, what we recommend is that for lightweight 1/10th scale vehicles where maximum acceleration is the most important aspect, the CM36 slotless motors are still best. For heavier cars, the 1406 four pole motors will be superior.
Thanks!
