Williams career mode ultimate AI

Hi guys. I just wanted to know if anybody out there has done a Williams career. I just wanted to know how the car feels and is it any good?. I have just finished my first season on the PS4 legend AI with no assists in a haas. I managed to win the championship in Mexico so I want to put it on ultimate for a better challenge. Any thoughts on ultimate AI using no assists on the PS4?, and Williams car in general.

Thanks guys
