It doesn't hurt to have a few on hand to swap around. many of soaps and creams I have tried last a bloody long time, so a bit of variety is good to have to try a new scent for a while. All I have currently, is Cella cream and Crabtree and Evenlyn Soap. I ran out of my Wahl 6 months ago, I still have Fauldings cream and Palmolive shave sticks as well, but they are either travel kit or back up, in event of a Zombie apocalypse and I can't get to a store for a while. I'm a bit of a minimalist...Like you I think...There are others who would scoff at my 'variety'.
