Everyone has there own opinion on what the best is. Generally that is what they have got, or what they would have if they could afford it, but that is just down to choice, and may well not be right for you.
There are other factors you need to consider, like if you are able to get the car set up correctly or if you have someone that can help with that. If not, then you might want to go for a more basic model. Also if you break anything on your car are you able to get the parts easily and cheaply. Might be worth considering what makes of chassis your LHS stocks, also they should have an understanding of that car and be able to offer some advice. Also I know its not always what people want, but if one car is popular at your local club, then you will have plenty of people who know how to help you.
If you want to see what the best car for the professional drivers is then have a look at what cars in in the A final of the big races. This will give you an idea, but it doesn't allow for a good car that doesn't have any of the top drivers using it.
