My five favorites in order of preference:
Feather
Gillette Silver Blue
Astra SP
Personna Red
Shark Super Chrome
I could happily shave with any of the first four exclusively. Feather is my favorite but I get fewer good shaves per blade and they are the most expensive. To me the Gillette and Astra are almost interchangeable. The Gillette is a little smoother on the first shave. Personna Red is very consistent and they were the first blade that I ordered 100 of.
