I would say go with what ever car you are leaning more to. If you change your mind and go with a different car then what you thought you wanted and you are not happy with what you got then you will more than likely dump the one you got and spend some more $ and get another kit.
I am slowly learning that if you dont like a certain car because of the way it handles stick with it start learning more about set up and get the car to handle the way you want it to, all of the kits that have been mentioned are all awesome kits, and in the hands of a good driver can out run one another. I myself was quick to dump a kit and not spend much time trying to get it to handle.
As mentioned in some other post be aware of some of the negative responses about some of the kits unless it is coming from a reliable source.
