Gazzew (Boba) U4: housing material

Hullo everyone, I’m looking at silent tactile switches and for sure one of the most recommended is the the Gazzew U4. I see that the white “Boba” housing plastic has been changed to a new one with better discoloration resistance. Does anyone have esperience with the new version? Particularly regarding scratchiness, I have a tester with the 62g black “Boba” plastic and I wonder if the 65g new white plastic could have some negative acoustic impact. Not a big deal, but I couldn’t find first hand experiences on the web.
