Better Just go and try and feel it, you won't know if you never touch it, although a lot info about the switch feeling. 
I just stand on the pc fair try out the switch more than 1 hour then go for lunch n come back test again. At the end I choose the led color not the switch....   ( just between blue or red in my choice at that time ) , and now just want get a blue switch for fun. 

Wakakak, reload reload!
Brown switch/Red switch

Do you must have the numpad? If not a TKL will do.

If got chance try them all, who know later you like the black because of you got strong finger to type on black like playing piano ~ 

keep in mind that general preference or other's preferences do not simply apply to EVERYONE.

though you might heard that certain switch is suitable for gaming, but that doesn't hold the ultimate answer for you if you never tried all of the switches

Good luck finding your perfect switch

Do you play dota 1? I don't recall dota 2 need to use numpad.

Anyway, blue should never be used for gaming, I mean, if you're a serious gamer, even if it's personal preference. I personally talked with pro gamers from UK, US with razer sponsorship, their feedback from using BWU.. you don't even want to know, they said they would prefer to go back to rubberdomes. But if you're just ehhhhh, not that serious about gaming, and got typing, go for it.

If you're from Penang, you can try ask kaiserreich for tryouts. He has a tryout numpad if I remember right, or you can meet up with him and he'll let you try his keyboards. You need to ask him first though. : x

A TKL keyboard is basically a keyboard, without numpad. It's better for your wrists, and space saving too.

LoL also doesn't use numpad. =_= I used to play it, but not anymore. I have a lvl 30 account in LoL NA. : P
