Out of the two I'd pick Filco. Better quality also doesn't have weird layout (SteelSeries), it has one extra key at where the right shift is so I'd imagine I'd keep hitting the wrong key if I were to press shift.
Though out of your gaming choices, I'd probably suggest you get a board with MX Brown. In my opinion for Tetris, Starcraft and Dota2 tactility would probably help. As for COD4 I guess black would be ok.
However if you're dead set on MX Black, Thermaltake Meka G1 or Mionix Zibal 60 would also be good choices
