black top white flopp

The black gets me 5 the white only 3 stars Why?
I'm just one of the differences:

black:
+ Better display (black value and no color cast)
+ The rubber backing is grippy than the whites.

white:
-Powertaste Is hardly out of the housing and is also more difficult to press.
-Laustärke Key rattles very strong and has a relatively long game 1mm
- Display has a light violet tint and is not really black.
- The cover is very slippery compared to blacks.

The only positive at the White: it looks prettier, unfortunately I not enough and thus I keep the black.
