Many members here like to regurgitate the infamous "it's all personal preference" response to this kind of post, and while personal preference is the ultimate trump card for all other switch attributes, it's not the only thing that matters. Linear switches (reds and blacks) are great for specialized applications, such as arcade game controllers that have no more than a few, distinguished (by large spacing and size) buttons. You may also notice some professional gamers actually remove keycaps for keys they cannot afford to unintentionally press, thereby isolating the group of switches they actually need to use. Fighting game controllers and osu! controllers are a great example of good applications for linear switches. The user of these devices knows precisely where all of the buttons are, and intends to push them (sometimes repeatedly) very rapidly, without consideration for the slight bit of keypress confirmation that tacitlity provides. Speed is the ultimate priority. Blues, for example, are terrible for "high action" gaming due to the hysteresis. If you're playing something with a much slower pace like an action-adventure game or something similar, obviously this wouldn't apply. This "speed" of linear switches is the primary reason you will see arcades in Japan full of linear switches such as those offered by sanwa. If you're gaming with a specialized controller, or only use a few keys on your keyboard, and need to "spam" keys frequently, linear switches are a great choice.
OTOH, on a keyboard that is also used for touch typing, the benefit that a tactile resistance barrier offers is invaluable. Touch typing sentences requires long chains of presses on different keys in exact order, and since you're not looking at the keyboard, your brain is relying solely on touch and sound. The challenge is not mashing out "AAAAAAAA" to buffer input into a tiny frame window so the combo connects, or timing a 4-keypress combo, it's typing a long-ass wall of text post like this with zero errors. It's accuracy vs speed. Of course both are important, but which is more valuable? It depends on your use cases.
That being said, browns are a great choice here because the tactile bump is not so difficult to overcome, and the hysteresis is so low. In general, I think people asking if they should buy reds would actually be more pleased and less error-prone with browns. I wouldn't suggest buying reds unless you are using them for a specific game/application in which it makes perfect sense, or just plain love that switch despite its shortcomings in touch typing.
The "personal preference" preference response is getting really dated. Personal preference defines every choice you make in your life. No ****, choice is based on personal preference. People posting here asking for which switch to buy aren't asking for you to choose an ice cream flavor for them, they're asking about intended applications of the switch, they just probably don't know to word it that way. Although even if they did, I'm sure the response here would still be something along the lines of "it's all about personal preference bro".
