Normal Eggs vs Egg White Powder

I've always preferred normal eggs because of the fact they are a whole food but am curious as to the disadvantages and advantages (if any) of switching to an Egg White Powder which is say 80% protein.

More expensive
Less fat
No need to cook

Don't know which of those are advantages or disadvantages for you...

I'm meaning in terms of nutritional value, less fat but surely normal eggs are better for you and building muscle

Egg protein powder is generally used by people who are lactose intolerant. For the rest of us, whey is much cheaper.
