For my face, Feathers require the most care, but give the best first pass shave. My current daily is the Bic chrome platinum, which I generally replace weekly, so 6-7 shaves. I can stretch them longer, but I find that I acclimate to how bad the shave is getting, and they are cheap enough to do weekly. I've also liked astras, but just never got into them from a value point of view. I'm thinking of switching to gillette 7oclock platinums (blue), I found they give a very smooth shave as well.
I use a Gillette 3 piece tech open comb. Thats pretty much all I've used, as I found that the couple of bar razors didn't work all that well for me. But that was at the beginning, might be time for a revisit.
