ON is very tasty, excellent company, mixes easy with little froth.
Dymatize is damn delicious, my favorite by far, a bit more pricey, also excellent company, but when mixed it does froth up more than ON. Both of these are my go to choices.
Not all whey is the same, they come in different forms. Hydrolyzed, Isolate, Concentrate.
Stick with the first two, higher purity, easier to digest, faster absorption, etc
