Bro you get some good and some bad. as we speak in my son's xt8 we have a Air 358 on steering and a 357 on throttle..for a year and a half now. maybe not the fastest or strongest but i can count on them which i think is very important..we have had the same luck with Jr also. and a 3 year warranty is nothing to sneeze at. i got two 9100t's to go in the new xt8 when it gets here. i dont think there is a best..
