I in the main agree with the posts already here, at first all you want is a lather that will help to offset poor technique, but eventualy you just want to try different things, I try to not replecate a scent.if I am buying different brands of soap/ cream, that way I can try 2 new things in one, I have some products that smell fantastic but are not impressive latherwise and vice versa, though taking into account ocdshavers point maybe I have judged products unfairly.
My goal though is to only have one soap and one cream.
But as they are so cheap comparatively, it is hard not to pick up something new when you see it.
All the best
