the t-spec is decent but there is no aftermarket program for it. so basically you cant upgrade it. it comes with adjustable camber, bearings, alumn driveshaft, ball diffs etc. i feel that the tt-01 would be a better buy though you would have to throw down some cash for upgrades at least there are upgrades for it. tamiya has some of the best quality cars, while trinity is known for their motors and batteries(EPIC/Trinity)

so yes i would say that the tt-01 would be better but go with the tt-01R. it comes with alot of upgrades. the t-spec is better in spec racing when you actually use it for its design, while i feel that the tt-01 is more of a all purpose.
