I've run both and both are TOPS. Out of the box, the LRP has a very nice feel. But the Tekins can be setup to feel very similar if thats what you're after.
Tekin has awesome CS, LRP is good too, but not quite as hassle free.
LRP has a nice heatsink that you can attach a fan to if need be. Tekin does not have this option.
So if you're like me and like to run stupid motors (4.5T) in off road 4WD, then it can be difficult to keep temps down on the Tekin.
If Tekin would add a proper heatsink on the the RSPro, it would be imho, the perfect esc..
