The genre and the vibe the two dramas give off are very similar. You have romance as the main plot with a political revenge plot going on in the background. The two FL's are very similar with their 'crackhead' energy. The ML's are very different though, which results in very different dynamics between the leads. Mr Queen had an enemies-to-lovers theme, while Unchained Love has saviour to lovers? All in all, I believe if you enjoyed one, you'll enjoy the other.
Although the storyline and everything is very different
Both depict the character of a historic political figure named Kim Jwa-Geun
FengShui is set in the last days of King Cheoljong while Mr. Queen was the early years
depiction of Kim Jwa-geun is different in both, as Mr. Queen tried to keep the light-hearted comedic touch in it
Both movies show a different ending to what happened to Kim Jwa-geun and King Cheoljong (idk which one is real but i'm pretty sure fengshui is closer to reality)

Not a gender-bender or time-travel. But in similar manner there are fake identity crown princesses, Mr. Queen is a man from the future inhabiting the crown princesses body, in Fake Princess the crown princess is a look-a-like that gets swapped in for the real crown princess.
In both stories the ML (crown prince) is suspicious of the FL (crown princess) as she comes from the "enemy camp". Also in both stories the ML (crown prince) is also under threat from enemies all around him and must behave low-key and plot secretly with few allies.
The stories are quite similar, romantic and funny with a more serious undertone, fight scenes, plotting, and mostly the pull and push relationship between the ML and FL where they battle suspicion and romance between each other.
