I've spent a couple of months with the standard sampler pack from WCS. Here's my verdict:
Merkur: Came with the 12C, so have only tried it once. Initially seemed to skip but then I got a nice smooth shave from it, and it lasted a long time. I really can't see why people are agin it.
Feathers: Wafer thin, very sharp, sure, but I got more irritation and red marks, and it lasted just a few days. But I'll try it again.
Derby: Very smooth, good shave, reliable, lasts more than two days.
Crystal (Israeli): Very similar to the Derby, I am not sure which is better.
Astra: Or is it this one? Also very smooth, despite the machine-oil smell.
Dorco: Oh dear, A dreadful blade. It cuts, sort of, but not very well. Ten passes may make a difference to my coarse stubble, but sorry, this one isn't for me.
So which for refills? Derby or Astra or Crystal all seem very similar, possibly Derby has the edge. And I wouldn't mind giving Merkur another go.
Of course just my $0.02 IMHO and YMMV.
