Yet they still have some uses that make them a decent choice when used creatively. Now, once you advantage over most other creatures when it comes to sight. That said, a average for many of the familiars in 5e, but they only have a movement and With a 60 ft. fly speed, the owl can fly very far away. Then I would suggest a frog as an option unless you wish to spend the time and resources to keep switching familiars.
