The three Reply series have been immensely popular and praised for the very accurate portrayal of life in those years (1997, 1994, 1988) in South Korea.
I will compare the three series and discuss the one I liked the most; these are my personal opinions so feel free to write your own in the comments.

At first I thought the drama was pretty slow but it sure picked up and did not disappoint at all! The concept was very original and fresh. I loved how you did not know who the main girl's husband was right till the end of the drama. Apink's Eunji played the main female character and her acting was surprisingly very good, it also helped how relatable her character was (fan-girling over all the idols). Overall I loved the show and recommend it to everyone.

After loving Reply 1997 and finding out there would be another drama from the same series I was very excited. After watching the first couple of episodes I realized how different it was; yes you still had to guess who her husband was, but I found the characters weren't as lovable. I actually found the main female character extremely annoying so I stopped watching the drama.

I was hesitant to watch this series just because I heard Girl's Day Hyeri was playing the main character and although I'm a fan of Girl's Day and Hyeri, I did not like her acting in some of the previous roles she played in dramas. However, after watching the drama I really started to like Hyeri's character as well as the other main characters. The many valuable lessons told in each episode as well as the portrayal of the lifestyle back in the day in Korea, made the show very interesting and fun to watch. The story focuses more on family and friends rather than just teen love, which makes the drama very refreshing and fun to watch.
Winner:
Overall I liked aspects from both the Reply 1997 and Reply 1988 series so it was really hard to decide which one I liked the most. However I would say Reply 1988 has been my favourite just because the characters are so likable and the drama never gets boring.
and how can you not love these boys...
