Same genre. Ever Night may have higher production values, but both are enjoyable for what they are. Very high quality effects and acting. If you're watching Oriental Odyssey, watching Ever Night in-between episode releases, is a must.

In both dramas...
• The ML starts out answering to the ML, in Untouchable Lovers he is her male concubine and in Oriental Odyssey he is her slave.
• Both have female leads that investigate and solve crimes, although in Untouchable Lovers they are less like investigations and more uncovering secrets.
• The ML falls in love with the FL and later loses his memory and meets her again as a prince.
• In both dramas the FL and the ML meet and fall in love twice.

This is a mess of a drama. However, Janice Wu plays an extremely likeable kick ass character with a heart of gold. Not unlike the main character in AGLM.
