I have the S10R ( bit bigger than S1R) and an S1 mini in copper.
very difficult to choose between them, they are both awesome lights, both great for EDC, build quality is outstanding on both, great U.I.
but......, I edc the S1 mini because its a bit smaller and dissapears into the watch pocket of jeans so you dont even know its there. doesnt see a huge amount of use but always there if I need it.
plus its Copper, has an amazing patina and is just the best thing ever !
S10R sits on nightstand for using around the house, dog walks etc, mainly as I dont have to use up a primary cell, recharging is a bonus for "user" lights.
sorry, I know havent helped much, you might need to get both. !
