I'm working my way through the WCS "Everything" sampler. I've tried at least one of each blade and now I'm using up the packs one at a time to get a better feel for the brands. I'm currently on the Lord Platinum pack and have been very impressed with the brand. I hadn't heard much about them before so they totally surprised me. For me at least, the combination of sharpness and smoothness is very good. The really outstanding feature, though, is the longevity of the blade. Most brands in the sampler only gave me 3 good shaves but the Lords have been giving me 5 good shaves per blade.
So far my favorites in the sampler are the 7 o'clock yellows, the Astra and the Lords.
