Best thing you can do is look for a car you can get spares for easily, that rules out probably three of your choices depending on your local stockists. In most areas in the UK the spares for the Tamiya, Aero and Predator are limited so if that's the same in your area then i'd stay clear and go for a car that you can easily get the spares for and that other drivers of the same standard are driving so you can share set ups. It's ok to follow the best drivers set ups for a base setting but you need to get ideas from people of a similar ability to yourself.
