There's a lot of webpages on the internet making recommendations to first-time buyers, but they tell you a blinkered version of the truth. They basically lay out the standard MX switches: blues, reds, browns, blacks, and maybe clears. They'll say "Blues are great for typing and are clicky, Reds are light and good for gaming, Browns are a 'middle ground' between Blue and Red as they have a 'tactile bump' for typing but no clicky noise." Truth is, Browns are simply a Red with a small bump, and none of those switches are particularly great in stock form.
All the criticisms of Browns posted on this thread are accurate. They are scratchier than they should be (although the post-2016 ones are not as bad as in the past), they barely have any perceptible tactile bump at all, they are not particularly satisfying to use. Basically, they have no personality, that is the truth.
On the other hand, they are ergonomic, they won't hurt you, and they are light. Once worn-in, they are even somewhat smooth. (New Browns are terrible until worn-in). They are a truly 'mediocre' switch: they get the job done, but without any style or pizzazz.
If the original poster truly wants to enjoy his keyboard, he should buy a big switch tester and try different tactiles. There's a decent amount of choice by non-Cherry manufacturers now. He could find out what he likes and order a custom.
But to answer the original question: Browns are responsive, but not very tactile. They're more sandy and scratchy than "mushy." Imagine a 'mechanical' keyboard that produces a consistent keystroke, but the keys don't go up and down as smooth as they should, and the so-called 'tactile bump' is nebulous. They'll never be as smooth as Gateron/Zealios, nor as interesting as some of the Kailh and OUTEMU options.
For gaming, they are fine. They don't get in the way, and I don't accidentally actuate them. More versatile than reds. But ultimately boring. BTW I typed this on MX Browns.
