A piece of paper, a big one, I don't know, a mouse pad isn't going to make a noticeable difference, it's just kind of a cool novelty to have one that matches your mouse or keyboard.
I think the mouse pad will be same if it uses same surface. Speed: it's smooth surface. Control is rough surface. The best important is which mouse pad suit for you in using.
cloth one with smooth surface, and large size you can try B-070 bloody gaming mouse pad, i also use their b-081 but that one is more for control, for speed i use the b-070. very smooth surface
