I have recently installed the twin point and find it a lot better. Steering is faster and more direct. I would also describe it as more linier throughout its full lock. This seems to give it the edge on consistency when pushing hard for me where the original system could make the car feel raggedy when pushing.
Admittedly the first few runs the car felt a bit edged with the twin point but you soon get used to that and now can't see myself going back to the original.
