I'm curious which aspect of shaving BBers think vary the most according to personal preferences.
For me, it's the razor blades. It's not easy for me to hear how one blade can be great for Joe but cuts up Al. But hey, that's just me.
There is no "all of the above" choice because I want responders to opine about which they feel is most important variable. It is clear that all of the above have a dramatic effect on shave quality, but I prefer to have more specific responses.
