I think the difference between the cars in the list for all but the very top drivers is irrelevant.
Car set up is critical. I really struggled to get my multi-adjustable car sorted. It was hard to control and as a result I crashed a lot. It was no fun at all to drive. Now I'm rapt with it. I'm really pleased I perservered, it is very satisfying to solve problems.
My best and final advice is pick the one that attracts you most - not what other people like, then work on driving and set up until
you are racing with similar spec cars, (as opposed to being in the same race).
Cheers
