If the switch is lighter then it's better.
Red is lighter than black and uses pretty much the same mechanism therefore it's better. This is not about opinions and preference but physical facts. If the button requires less force to be activated then your endurance on streams or 1/2 will be better.
What is, indeed, about preference, is choosing between blue or red. Using red switches means you gotta bottom out the key for it to work, on Blue ones you don't.
Most of what people will tell you about this is pure crap, I've tested red, blue, black, buckler-spring (those old IBM switches I don't know how they are called) and I wouldn't even think about getting anything besides red or blue. Not talking about brown switches since I barely used them but they are kind of a mix between blue and black so meh. If you want switches which are just better go with either red or blue, rest are not as good as them for osu!.
