I've spend many weeks, months actually, trying out various blades- about 20 in total. One thing I've determined is that I don't have a favorite blade, or even a "worst" blade. Most work well for me, but I have finally narrowed down my likes to five blades. They all work well for me and it will take more time to see if any is really my favorite. Had a hard time deciding which to order as the first 100 of "my favorites" but finally settled on ...
Perma-Sharp Super - I love these blades. They seem as sharp as any I have tried, at least if I measure that by closeness of shave. I always get an incredibly close shave from them. They are also about the smoothest blades I've used and leave very little burn after I shave - perhaps a bit with Alum or alcohol, but that is mild and momentary, and then nothing afterwards like I do from some other blades. Finally they seem to work well for many shaves. Given that they are cheap to begin with ($20/hundred) and last a long time, they represent a value buy too. Just placed my order for a hundred of these.
7 O'Clock Yellow and 7 O'Clock Blue - I will order 100 of one of these soon. The only reason I didn't also order 100 of one of these is that I can't decide which I like more. Whichever one I've used last seems to be the one I prefer. Working on a Blue now; so today it's Blue. But there have been several days when it's been Yellow. Maybe I should just resolve to get 100 of each and spend a year or two trying to decide which I like better.
FYI. The other two I like and may yet order in quantity are - Personna Meds. I want to try Labs first to see if I like these as well. They're about half the cost. So I'm hoping I discover I like them as well as the Meds (Yes. I know they are supposed to perfrom the same). And lastly I love the new St. Pete Gillette Rubies. The only reason I'm not buying those now is that I know someone who can get them for me in eastern Europe for better prices than here.
So that's it. My first 100 "favorites" ordered, and at least the rest identified ... for now of course.
