Having used both, I feel compelled to throw my $0.02 in: I can't tell the difference between them when it comes to the shave, but I prefer the Norton due to its harder feel & easier soaking/lapping regimen. To me, it's more of a non-complaining workhorse--I always use it when I have a finicky blade--some technique on the Norton will always work for any usable blade; it's just a matter of which one the razor likes. It always works in the end, though. Always. It's also cheaper, which seals the deal in my book!
