I can't imagine there would be any benefit to getting a cotton/wool blend over 10% wool. With cotton it will be less wrinkle-resistent, won't wear neither as warm nor as cool as all wool, and it won't be as durable. I can only imagine it might be cheaper, though if it's a good quality it will hardly be cheaper. There's no good reason for it.
