There's a lot of good cars out there, so I guess it all depends on your preference, your budget, and what you will be using it for.
You should first check around your local hobby shop ("LHS") and see what they carry. Breaking your car and then waiting a week for a part to be shipped to you from Hong Kong is NO FUN! If your LHS stocks the parts, then its just a trip to the store.
Now, if you intend to race, you may want to check out the local races and see what everyone is running. They will be able to help you in the future with any problems if you are running the same car.
If you are drifting, you should consider the new TB-02 drift spec car, as it has some hop-ups that you would probably buy anyways (drift tires, aluminum shaft, TRF shocks). If you are road racing and looking specifically at TCS racing, then I would go with a TA-05, as it performs beter and is easier to drive.
