what the evidence says
Whey isolate carries the same strong evidence as whey generally: what trials reward is total daily protein alongside training, and isolate's extra filtration mainly buys less lactose and slightly more protein per scoop. For the lactose-sensitive that is a real benefit; for everyone else it is a preference, not a performance edge. Zero Carb's niche is cutting phases where every non-protein calorie is being counted; the evidence for that level of precision is more psychological than physiological.
