Volume wheel is usually only used outside of games when listening to music. Because when playing, its going to affect both the music and game sound.
To be looking at these high end keyboards in the first place, the cost premium to get a preference or minor feature is usually ignored. For your case, you are paying more to get a more robust product. If longevity is what I am looking for, I would rather pay the extra ~13% and not worry about the keycap paint chipping off, wristrest clip breaking off, or cable getting damaged within the years of use.
