120a esc advice
 

currently have a hobbywing v3.1 1s is the boys gt12, buggy season is coming close so looking to buy a esc that will do his 1/10th buggy and gt12 (obv will use a 1s booster for it)
atm I am looking at ether trackstar gen 2 120a or trackstar turbo v2 120 , anyone know the difference between them apart from it looks like they use different programing boxes ?
also the hobbyking x-car beast 120 is looking pretty similar.
