They are both survival shows from the same company (iQiyi), with similar styles of editing and content. However, there are different trainees and mentors in each season.

For those who liked Lin Yanjun, I found most people also liked Luo Yizhou ;)

I would like to first address that Memory Lost is a series and when I refer to its title, I am referring to the entire series and not just season one.

Both of these stories were written by the same author, Ding Mo, and turned into dramas.
They are similar in that they are both a crime investigation series, and follow a string of crimes that connect and eventually lead to the main culprit. The female leads in both stories have a specialty in psychology, and at first, the male leads in both dramas develop some sort of disagreement with the female leads' psychological analyses, until later when they gradually learn to appreciate it.

The one difference would be that Memory Lost is definitely a lot easier to follow and understand compared to When a Snail Falls in Love because it spans over multiple seasons, allowing the story to unravel leisurely. The story and relationships in When a Snail Falls in Love were complied into one season, leaving everything to be more fast-paced and you would have to really pay attention to fully understand the entirety of the story.

It presents the same concept but is simply a female version of the show. Instead of nine people, eleven trainees end up debuting. The show is definitely emotional, more so than Idol Producer, as it can cause you to tear up some times. The teachers are amazing and funny, and support the girls so much.

It's a show featuring the debuting group from Idol Producer, Nine Percent, and their life in America. The show presents clips of Nine Percent at Universal Studios, practicing choreography, and recording music in studios.

It is definitely super funny and showcases the individual qualities of each members.

These two dramas are similar in that they share the same concept of school and growing up. Although, The Big Boss is purely a comedy, it does have an underlying concept of a male and female lead eventually liking each other. The difference lays in the fact that A Love So Beautiful is majorly about romance, and how the leads fall in love. Both dramas have very unique and silly female leads, as well as smart and handsome male leads. The group of friends in both dramas are amazing and funny; and there is not much rivalry over the male lead in, unlike most romance dramas, although in A Love So Beautiful there is a little rivalry/jealousy when it comes to the female lead.
