I believe that Mage/Cleric is overall superior to the Mage/Druid. Two good druid only spells are ironskin and nature's beauty. But a mage already has it cover with stoneskin and blindness/power word blind. A druid would really benefit if he has access to cleric only spells such as DUHM and Righteous Magic.
The only good thing about M/D is that he can wear the Robe of Vecna and Amulet of Power to instantly cast insect plague and quickly cast creeping doom.
One can optionally use Shadowkeeper to become a Mage/(Cleric)/Druid. Simply add the druid spells to the spell book and remove the cleric spells. Weapon selections are a bit gamey. The only way to use druid only weapons is to give oneself UAI and assign pips in Shadowkeeper. There are probably mods that allow M/D without the hassle of messing with Shadowkeeper.

Maybe a Druid/Sorcerer
