Due to different processing methods, whey isolate is more concentrated (more grams of actual protein per gram of powder) that whey concentrate. It might be a difference of 27g protein per 30g scoop vs. 22g per 30g scoop, so the efficiency of taking isolate over concentrate is negligible.
Isolate becomes useful for those who are lactose intolerant, as the processing leaves the product nearly free of lactose. Isolates are also used lunatics that won't intake the 3g of carbs found in your typical whey blend. Isolates might digest slightly faster, but perhaps too fast for anything but a post workout shake.
The real difference is the price. Isolates cost way more than whey blends. Whey blends (containing a mix of isolate and concentrate) are the most common proteins sold because they are effective without breaking the bank.
Another more expensive blend might feature micellar cassein, possibly along side whey, which digests more slowly. Due to their fat content, no protein shakes taste better than these.
