I understand that they can not be ranked, but it seems that blues are the least desirable, due to inherent attributes
On the contrary. Blues are far and away my favourite Cherry switch.
black and brown are often described as being ideal for gaming
Blacks are described that way by *some* people.
Browns are not 'ideal for gaming'. They are just considered by many to be a middle of the road compromise. They are 'ideal' at nothing in my opinion, but are not awful at anything either.
reds seems too be highly sought after
Yep a light linear switch that is some people's favourite.
then whites, clears, greys, greens and possible others i have no idea about.
I understand that it is a preference, so i ask, why do so many people prefer reds? Many people on the forums were complaining that CM boards with red were Asia only.
The people complaining were complaining because they like the red switch.
Maybe you will like it when you try it. Maybe you will hate it.
Focus less on the colour for the moment.
Do you want a switch that is tactile or linear?If you aren't sure what the difference is then do some research into those words here in GH.
Once you have made that decision we can focus down on what the options are in the relevant switch type.
