Never tried OSP but very recently had the displeasure of two Salter creams... Sandalwood smelt of sweet cinnamon, didn't even bother lathering it. Wild rose had a strong base scent coming through - Reminded me of Savlon! Used it once, very runny in the pot, like hair conditioner... Good glide but poor protection and dry post-shave.
If your choice is definitely limited to these two manufacturers then I'd give OSP a try.
