The real truth of it is we can tell you a lot of technical things but after driving a vehicle with a better radio you wont go back, I was driving with a cheaper radio back in the day and I am going to date myself here, and a friend let me use his Airtronics m8 it was the best there was on the market at the time, anyways he let me run a race with it, I came off the driver stand and said I would be right back and walked inside and plopped 4-500 bucks on the radio in the hobby shop and never doughted the purchase. a good radio which you can get good entry level from airtronics, futabe and have heard good about the graupners as well, the radio just feels different when you drive feels like you have better control and are more at one with the car, but you have to have a decent servo to go with it.
