cant really comment on the derv's but imo the cupra handles pretty good. my handlings about to get a lot better right enough as im about to fit coilovers but its more for looks as i very rarely push the car to the extremes of its handling capabilities. 
only thing i would say is its pretty harsh and at times it feels like your getting the sh1t kicked out you......but i kinda like that....except when im hungover!
