Carol,
Here's a link about the Cherry MX switch types (black, red, blue, brown) used in gaming keyboards.
Cherry mx blue, red or brown - [Solved] - Computer Peripherals
The keyboards you have linked, may not be the Cherry MX brand of switch, but if the manufacturer stuck with the same color reference, that might give you an indication of what to expect from the keyboard you pick.
Of the keyboards you picked, the first one says "blue switches", and may give you the audible click when pressed. Your second and third choices, keep the receipt
.
Newegg is having black Friday deals all month long. If you don't need the keyboard ASAP, there might be a deal pop up there.
Thanks
