Whey vs. Isolate

[motocrosser]

What's the biggest differences and is it enough to justify to pay more for isolate or over-rated?

isolates vs concentrates is what i'm assuming you are talking about
isolates absorb faster so post workout you'd be better off with an isolate or better yet, hydrolised whey but that costs more than isolates
