Best gt4 for begginers

Good evening, I just entered the iRacing realm 5 days ago and I am fucking hooked, I love it! I got my d-license and want to drive some gt4 series. Which one of the gt4 cars ist not to hard to handle and in general good and fast enough to have fun with?

Bonus question: Do people race tcr? Wool like to jump in the Audi.

Thanks!
