I think I've tried the Astras, but I'm not sure. Years ago I bought a blade sampler from West Coast Shaving (
https://www.westcoastshaving.com) and went through what I got. I remember that I thought the BIC, Gillette, Derby, Shark, and Merkur blades were all sort of midpack. The Feathers are very nice and sharp, and I thought the Israeil "red pack" Personnas were up there, but not as good as the Personna Med Preps, which I've stuck with. I remember hating the Dorco blades I got. I don't remember if Astra blades were part of that. The Med Preps are on the expensive side (if $45 for 100 blades is considered expensive), but they're also made in the USA, if that matters to anyone.
West Coast Shaving has lots of good stuff, and I can recommend the company if anyone needs shaving supplies.
