I agree, neither. Traxxas brushless esc's are junk (trust me. Between my friends and I we have gone through like 4 of them with simple street bashing most of the time dry as a bone).

I had my sidewinder sct (sv2) and it runs HOT on 2s even with a fan on it. I sent it into castle and am paying $75 to upgrade to a mmp esc. But I think that the hobbywing is a great esc for the money. (all of those vxl esc's got replaced by hobbywings).

Oh, also my friend did send in one of those vxl's UNDER WARRANTY and had to pay $55 to have it fixed and it took over 3 months (yeah, months) to get it back. It took weeks after the shipping confirmed that traxxas got the esc even to hear from traxxas. NOT a good experience.
