You won't find many people here recommending WASD keycaps. They're made of thin ABS (a plastic that will show wear and shine after continued use) and are lower-quality than other keycap sets at similar price points. I don't love WASD's colors either; I don't think they compose well.
That's just, like, my opinion, man. Ultimately, it's all down to your personal preference.
