Do you have any issues with your braided hose?
If you answer no, then there is no advantage.
Do you fly sparge? If you do, then a properly designed manifold can limit the channeling that can occur with a braided hose. If you don't notice a problem, you may not have one.
Batch Sparging pretty much drains all the wort anyway, so channeling is not a consideration.
Bottom line is that if you are happy with what you are using, there isn't any good reason to change. Even if you were to get 5-8 more points of efficiency, it's not enough to warrant a change IMO.
