A heavier swing weight for me usually means the racket can produce a bit more effortless power, AS LONG AS the person playing the racket is strong enough to give it enough swing speed. For instance, if you're trying to play badminton with a 150g training racket, even if it's heavy it won't hit as hard as a 90g arc11 because you likely won't be able to generate enough swing speed for the training racket. But as long as you are above that threshold for strength, it's good. So I guess you could say the 88s will hit more effortlessly in terms of clears, smashes. It does not necessarily mean it has a higher power ceiling than something with a lower swing weight, because in that case shaft stiffness has to come into play as well, and the 100zz does seem stiffer than the 88s, which means the 100zz could still have a higher power ceiling, despite swing weights. But honestly based on the stiffness of the 88s and 100zz i think only players who can swing as hard as professional male players would be able to reach anywhere near the ceiling, so it may be a moot point for most buyers, in which case the swing weight is still the more reliable number to see a racket's power. So in conclusion: yes, the 88s will probably hit harder for most people than 100zz, unless the 100zz does actually have some difference-making technologies. In which case you need to wait for racket reviews.
