They are some of the best I have used
I got my start using keyboards with Cherry MX Blues(Matter of fact, that is what I am typing on right now -- I was in the mood). I have, since moved to a keyboard with Kailh Box Whites in it and, as far as I am aware, those may be my favourite switches. I just recently got these Gateron Greens and some Kailh Speed Pink switches from Drop, but I haven't had a board to mount them in. That said, giving the switches a go all by themselves, I must say that I love the heaviness of them. I think that the Speed Pinks sound better, but it may be the case that the Greens feel better. I am currently thinking of them as "better" in a good, better, best kind of rating system. So, thinking of 3 starts as Cherry MX Blues and 5 stars as Kailh Box Whites, these Gateron Greens would fall squarely in the 4 star rating.
Would recommend to a friend.
