well it depends...
Like all electronics, you should also consider the if your country has technical and customer support of those brands...
Budget is also a factor... how much and what sort of track and amount of playing time you are gonna clock with the car...
Then there is the factor of what sort of cars/chassis people in your Local Hobby Shop (LHS) use too.
There are many established brands out there... for instance...
X-Ray (T2'008)
Tamiya (TRF 416; TA05; TT-01)
Hotbodies (Cyclone; Sprint)
...etc
You have to consider all of the above then decide.
