I think the thing I love most about my DS3, and I'm sure not many will have this opinion, is that the LEDs fully encompass the entire key and shine through fully, but not overwhelmingly. There are some keyboards where the LEDs literally shine light through that could potentially cause eyestrain or blindness!!(ok maybe not blindness :p). Some LEDs bleed so badly that it looks cheap and crappy, but these are well contained in each and every key cap.
My G15 wasn't bright enough with it's orange LED backlighting and I always wished the LED was stronger so it could fully embody the keycap, but it never did. The DS3 fully illuminates each and every key and looks beautiful.
The red is RED. There's no off red. It's red. I've seen other mechanical keyboards with "red" LED lighting, but it was an off color red, either washed away red or practically orange. Was not pleased. These are fully red or fully blue or w/e color you choose it is THAT color. It looks great.
This keyboard looks great sitting in front of you, but some modes look better farther away. If you're looking at your desktop from a bit away, the breathing mode and the wave mode look amazing from 7 feet away.
