Lackluster. It's essentially just a weaker Wizard who can turn into a Familiar.
To your point..wizard is waaaay more powerful then its supposed to be. They are definitely NOT supposed to be learning cantrips and cleric spells from scrolls.
Other then that id say they are actually pretty equal if you go circle of the land. Just waaaay more survivability as the druid since you can essentially have something like 60hp to burn through
