I have both team powers and Lrp in 4.5, 5.5t. Lap times for me both brands the same, but motor behave differently.
Team powers compare to Lrp feel less torque but higher rev, and also less drag brake feel.
Both brands are low maintenance for me but for Lrp need to be careful on the bearings.
If you are using Lrp speedy, Iwould suggest to get Lrp motor, but with hobbywing, speedpassion, tekin, or team powers speedy, get team powers motor.
