I like both reds and browns.
For typing, I have to say I personally prefer the browns. The slight tactile feedback is just enough to make the typing experience that little bit nicer. Also, while force necessary to register a keystroke is similar, the browns feel a tad bit heavier and I do not unintentionally push a key through the tactile bump. With the reds however, I can not help but have a lot more accidental keypresses. There is another things about the tactile feedback that I like. Somehow, almost subconsciously, I know when a keypress is registered which prevents me from bottoming out. On the reds, without such feedback, I always bottomed out on every single keystroke. While the slight tactility gives some audible noisy feedback, I found that the majority of the noise comes from bottoming out. All in all I think the two switches are equally loud for me, maybe the browns are actually a tad bit quieter because of the thing I mentioned. Neither one will be as quiet as the keyboard you are using now unless you can manage to never bottom out.
For gaming I like browns better as well. Reds feel more "immediate" and "instant" since it feels like a key is registered the moment your finger hits the keycap. This is great for example FPS, general WASD movement, using hotkeys in MOBA's etc. However, there are some games where I do not like it so much, and I would like to avoid accidental button presses and such. This is for example in some RTS. Here I like the feedback from the browns more, just like I do when typing. I actually end up doing more actions per minute on the browns, because I use them with more confidence and less caution.
This is of course, just my opinion. But that is really all anyone can give you on the subject.
