I still say that Ohlins is a great choice which of course everyone agrees with, and KW as well is very very smooth. Only disadvantage is that I believe the KW's are twin tube, which is perfectly fine for the street, but isn't going to be as good when it comes to performance against a mono-tube shock. Between the two I'd still say that Ohlins has higher quality parts which is why companies like Lamborghini, Ferrari, Pagani, Ducati and so forth, use them for their factory cars.
