The original MAKERbuino buttons are super-clicky for a real retro gaming feel (I suspect they are 260 gram-force).
If you want a slightly softer touch, but still with a definite click, these buttons are the next level down on clickyness:
Omron B3F-4050 - 12x12x7.3 Projected type - 130 gram-force

You will likely pay more for shipping cost than for the item cost for the 7 buttons, so plan to batch your order with some other goodies like solder, flux and solder-wick.
