From what i understand 5 =/= year of the goat..
I liked the ducky 4/5 and year of the goat/horse. Also k70.
Any noticeable difference between each or just a matter of preference?

whoops ur right

k70 has keys above the backplate, most other keyboards have them sunk into the frame, it's preference

i like my k70 but it doubletypes certain letters and it gets really old sometimes.. plus the r key red led channel broke after like 2 days, had it for over a year now and haven't bothered warranty'ing it.

I've never experienced any double typing with my K70 RGB. You're either holding the switch at the actuation point too long or you've got a short somewhere.

I have a k70 for the past 2 years. Best keyboard. It's the non RGB one that was $300 I think 2 years ago. Has all red keys. The build quality is fucking unreal. All the lights work on it, every button, the whole 9 yards. I've jizzed on this thing minimum 5 times. still works like a champ.
