There's probably no one-size-fits-all answer. Low carb seems to be across the board the most effective, but some people do better when they can feed their carb cravings with good sources of carbs like roots/tubers. And even some people who do the whole very low carb/ketogenic diets have seen improvement introducing good carbs occasionally, or when weight loss has stalled (don't ask me about the science behind that, I really don't know other than it might be tangentially related to some sort of hormetic effect).
So in my opinion, I'd say if you're doing low-carb already and you're feeling good and making good progress, might be a good idea to hold off on any changes for now. On the other hand, you may handle them fine, and so long as they don't throw you completely off the rails I don't see a problem with experimenting.
Sorry for the wishy-washy answer but people seem to vary a lot with this.
