Ideal for gaming are red stem cherry switches. (I don't think Filco have those) - they are lighter blacks, non-tactile.
Then, I would recommend browns, because they are the ideal compromise overall.
The blacks are better for gaming than browns but the added force necesary is tiring if you play a lot ...
And you know you will ...
So, for gaming: red, brown, black, clear, blue.
For touch-typing: blue, brown, clear, red, black.
Overall: brown, blue, clear, red, black.
For the cherry gamer
the ultimate keyboard is the g80-1800 programmable keyboard with red switches. If you can find it ...
Even better, the g80-1865 with a 2 port usb hub, but I don't know if it's programmable (I would choose programmability over a USB hub).
The G80-1865 is available with at least browns ... here:

The G80-1865 is rebadged by Raptor Gaming as the K1 - and in that version it's programmable and it comes wih wasd keycaps, keycap puller etc.
Officially it's a black switch board, but browns have been known to be in it ... as you see here:

The TG3 BL82 / DECK Mini black swich keyboard modded with brown springs, for lighter touch.
Question: Is such a mod easy (provided you have brown switch springs) ?
