Both shows may seem different due to Soredemo Sekai wa Utsukushii having the romance/ shoujo genre, while Sanzoku no Musume Ronja is more in the "children show" genre.
BUT:
Both Soredemo Sekai wa Utsukushii and Sanzoku no Musume Ronja have fantasy/ adventure elements and a comedic, relaxed pace to the show.
Both also have an adventurous, strong willed MC heroine as well as similar & great soundtracks and songs played within the anime.
Also I believe both shows are underrated anime gems!
