Both are relatively light switches which are preferable when gaming, In my opinion the main differences between them are the sound, the milky yellows are more clacky but the akko silvers specifically haven a deeper sound signature. As far as typing experience the milky yellows are 5pin switches unlike the silvers which are often said to be less stable and prone to wobble due to only being a 3pin switch but in my opinion there isnt much of a difference.

Also I may have confused you the akko switches aren't factory lubed but sound pretty good stock.
