Aside from both being fantasy/romance/mystery, both gave me similar vibes, but they do have some differences.

Similarities:
- Both are Fantasy/romance/mystery dramas, with more mystery in the beginning and more romance towards the end
- Both have creepy fantasy elements and involve heavy emotions/decisions which gives them a similar vibe at times
- Both involve a non-human character
- Both dramas involve a main character looking for their parents/parent
- Both involve exploration of afterlife, gods, and have similar depictions of the journey to death (on a boat in a river)
- Both dramas involve quite a bit of saving

Differences:
- While TOTNT has some historical backstory, it is set in modern time and Arang is set in Joseon time
- Arang involves more slow burn romance where TOTNT the main characters fall in love much more quickly
- While Arang also has fun side characters, it feels much more contained/focused on the main characters while TOTNT has more of an ensemble cast feel

I would recommend these dramas if you think the similarities are why you liked one or the other drama, but if the things that are different between the dramas made you like one or the other drama, I would be hesitant to recommend it.
