We demoed the new brushless Makita saw a few weeks back and found it to be pretty impressive for battery powered, but havent ran anyone elses to compare it to. We did notice that it has an overload protection on the motor and trying to push to hard it would kick out and force you to release the trigger to reset it, kinda annoying but if it keeps the motor from overheating and helps provide a long service life then its worth it.
I have a few of them ordered and should be in next week. We are planning on doing a little comparison video of it to the PS-32. See how it stacks up for cut times and battery life compared to a gas counterpart.
