Backlighting only serves as an accessory for me, it looks nice but I don't really need it.
I use the tenkeypad often while typing to make the following symbols °, →,↑, etc, but I have been looking for alternative ways to use the tenkeypad functions on a keyboard without it.
60% typing/ 40% gaming
Look, everyone here pretty much is biased towards their switch of choice. That's why I'd recommend Blues, because you type more than game, but Browns would be great (honestly probably better) also depending on the nature of the game. I've never had issues using Blues in League or RTS, but they weren't good on FPS.
If you want numpad functionality, take a look at the CM Quickfire TK. It has a unique TKL design, by having a numpad with the nav cluster and arrow keys integrated, so you actually end up using num lock a lot. Plenty of good features like lighting up the arrow keys only when numlock is off, an Fn lock only lit when in use same with the Windows Lock. Fully backlit, and generally under $100, great quality for me.
They have white/black versions, white has white backlighting and black has it the same as the switch color (brown is white, no black).

EDIT: Man, didn't see how old this is. What'd you end up getting?
