I have both Tekin and XeRun 120A. From my experience Hw has more rips out of corners compare to the Tekins.Yes Tekin does have a slight top end speed (you need a very long straights just to notice the difference)compare to the Hw IF YOU ARE USING THE SAME FDR FOR BOTH ESC with the same motor. My finding is you need to gear at LOWER FDR for the Hw (found out, it also lower the motor temp).This is not a problem in the in field as the HW has more acceleration rips out of corners while my Tekin is softer. Temperature wise Tekin is cooler I can't argue with that. My conclusion both esc's performance is about the same providing you find a sweet set up for both BUT the HW being cheaper I ll go for the Hw anytime. Also Hw has heatsink with fan so I can bolt on any of my mod motor as low as 4t with stock boosted fw without any overheating cutoff issue and it is crazy fast
