I would recommend the Leopold over Razer any time. It's not that much more expensive, and the build quality is far better. For switch type it's more difficult to recommend, but brown is usually the safest choice for first mx as it's pretty neutral. I've had all of the common mx and my order of preference is red, blue, brown, black. Which is nearly the opposite order I got them in (black, brown, red, blue). I like the red most for gaming as it is light and smooth, it's also fine for me for typing, but for just typing I like the blue better as I seem to make less errors with some good feedback. Brown is sort of halfway between. Blacks are ok, but I personally like the lighter red much more for a linear switch.
