Reply to Chroma Caps vs S2 standard knobs

So here's my dilemma.

I'm going to be ordering an S2 on Monday from DJTT. Now I really like the look of the S2 with black knobs the most, so I was believeing about just getting the black chroma caps. But then I got to believeing; maybe I should get the white/grey ones just in case I ever wanna change.

So ultimately here's my question, how much better (if at all) are the chroma caps compared to the standard S2 knobs?
