the main characters are similar because they are both wandering men who are seemingly naive but aim to help those around them. they also gain beautiful women admirers as they travel
Both anime series' have a protagonist who come off as extremely clumsy but somehow manage to get the job done.
Both also include a traveling protagonist looking for work who also are popular with women in their own bizarre ways. If you like the art style, both are very similar to each other!
I'm surprised that not many people compare the two! :D
