"Advantage" implies a competitive aspect, which in BnS means gaining gear faster, completing content using hacks or using skills that shouldn't be available, speed hacking, flying, etc.
On the other hand, quality of life can mean things that make your sanity drain slower, like for example faster jewel feeding into accessories you're upgrading, so that you don't need to afk for five minutes when upgrading stage 6->9 for no reason whatsoever. It's just waiting with no purpose whatsoever and no input needed from the user.
That gives you no "advantage", it just makes you less frustrated.
Cheats bad? Yes.
Not wanting to endure horrible game design effects? Grey zone, apparently.
