Right now, I'm using the first mechanical keyboard I ever bought (first one I used was Model M when I was a wee lad). Ducky DK9008 with Blues (sky blue) w/ stock caps except the red ones. It came with a Cherry MX Black spacebar, but I modded it into Greens, and now Blues. Bought it back in 2011, it looked awesome then, and it still looks awesome now. I'll never let this one go, as it holds a special place in my heart, and it's still super fun to type on... when I type on it, which is almost never anymore
Another reason I won't sell it is because this is by far the best feeling Cherry MX Blue keyboard I've ever owned/used, and I've owned/tried many blues keyboards (Filco, Das, Leopold, CM QFR, XArmour, Razer, Ducky Shine II). I don't know if it's because of the older "sky blue" switches, or if it's just the construction of this keyboard, but it definitely has the most pronounced and crisp tactile click out of all the boards I've tried. Every switch is clicking perfectly and going strong.
NOT MY PICTURE but it shows the LED on, which I couldn't be bothered taking pictures of:
