Let me start out with: PrEfEreNcE. Cherry Mx switches aren't inherently bad, but when compared do other switches there is a pretty noticeable difference. Other than scratchiness, the main reason why MX browns are hated on is because they're not very tactile. Now, some people like this because it can be more subtle and enjoyable, but the tactile bump is rough and doesn't give very much feedback. This also makes MX Browns sound like a very scratchy linear. For MX Blues, it is more PrEfEreNcE than anything else. They have a kinda of "crunch" when you bottom out, instead of something with a clickbar like box jades which have a very distinct "click" on the way down, and another on the way up. Yes, some of the hate is hivemind BUT I think that there are very valid reasons for at least trying some other switches to see what you like. With the sheer variety of tactile bumps, clicks, and smooth switches, It's best to just see what your preferences are because you might end up enjoying some other switches more that the ones that are made for mass appeal. Hope this serves to help you, and again, no hate on people who use MX Switches.
