If you are rolling scores then your wizard with mage armor can have an 18 dex if you are willing to press the button enough. That puts them at 17 AC, which is tied with wizard in half-plate with 14+ dex. The only advantage of wizard in half plate is that they don't need 18 dex, and they don't have to spend the spell slot. It does not make them significantly tankier though.
