I love 'em. Got about 1000 on hand and they just dropped in price again. Buying more. They're really great blades.
About all I can say is I like 'em both. I think the Blues might be a bit sharper, but I haven't done any kind of scientific comparison. My guess is that if you like Astras, you will probably like Blues, at least as much. They're cheap enough --- give 'em a try.I never used Personna Blues... I wonder if anyone in their experience could compare them to Astras?
