What’s the difference in sound between normal and sound edge Paiste 2002s?

I have a pair of Vintage 14” 1979 Black Label 2002 Medium Hats, absolutely phenomenal, but I’ve been thinking of getting some 15” Hi Hats too, and I’m thinking about the Sound Edge 15”s, either those or K Sweet 15”s. Just want to know if anyone has anything to say about them :)
