I've tried loads of noiseless pickups from various companies over the years and the best I've come across (ususally Dimarzio) have been 'ok and useable'....but not quite there compared to a good traditional strat pickup.
These seem so far (haven't had them in very long) to be the best yet, and unlike so many strat pickups claiming to be 'hotter' and packing more 'punch' these actually do that without being shrill or mushy. They just sound good with a balanced full tone while retaining a strat character.
Dare l say it...they remind me of SRV's sound, even on a low volume clean amp setting. Other so-called 'texas-style' pickups never seemed to deliver that in my experience.
So if you want a punchy, smokey-blues tone to fatten up your strat....and no hum...give these a go.
