I find the Chinese Schicks feel sharper to me, but the Personna's have their fans as well. Some of the vintage Schick and Personna blades are really great, but you have to pay pretty high prices for them on the bay.
I'm eight shaves in with my Shick M-2 Adjustable Injector with a Personna NOS Platinum Chrome blade and I'm just loving it. the shaves are smooth and comfortable. Why'ed they ever quit selling these razors in the States. Had I started shaving with one I never would have switched. Clayton
