apart from aesthetics, no
Usually i pick black keyboard but for Poker II, i decided to pick white version.
Its a matter of aestheticism, not everyone likes white version
Black Poker II comes with PBT keycaps and its rather dark grey than full black
With black case, its contrasted and i quit dislike it.
White vs Black keyboard, in my opinion:
+ easy to clean up when keys get dirty, you ll see it immediately
+ more beautiful (still a matter of taste)
+ pretty rare for high technology stuff that usually comes often in black version (TV, phones, consoles...)
+ sightly brighter into darkness
- its more complicated if you want all your stuff matching color with your keyboard, meaning desktop, screen, mice...
- get dirty quicker if you are lazy to clean up
- can yellow over time but at least it will becomes less white than new white stuff for sure (i had white iPhone and within fews month of use, it clearly less white than other newer white phones)
