I've been to the pub so I'm in no state to explain but I read a lot about it after my wheel kept slipping from my Hope open cam QRs on my Salsa with horizontal drops. Switched to Shimano and problem solved (although they look worse). Admittedly its not single speed but my single speed MTB pub bike has a shimano QR too and thats never let me down either and thats been on there for years. I do clamp it up a bit tighter than normal though (like almost difficult to release - but most ppl over tighten QRs anyway so its probably not that tight in the grand scheme).
