Depends on your driving style, ZZ5's are great as an everyday tyre on a performance car, handle wet weather very well. However they do not offer great grip compared to the Eagle F1's, but F1's are not brilliant in the wet. I have P-Zero's at the min, and they're good, but we use the Michelin Super Sports at work, and they will be what I put on my car next. Amazing tyre for grip if you drive your car fast! not great in the wet though, and avoid the sport cup's if you do any road driving in the wet.
So to sum up, if you drive your car like an everyday car, they're fine. If you drive it like a sports car, maybe go for something a bit higher spec'ed.
