I started out with MX reds in all my keyboards because when I got started with all this a couple of years ago, I really thought I was a linear guy. But then I tried a Topre board, I haven't gone back since either. With silencing rings installed, they make exactly the right amount of noise for me, which is to say very little. No discernable upstroke noise, and only that lovely soft thock on the way down. I don't know of any other switch that has these qualities.
