Everyone keeps comparing these three (and How to Dress Well), but as similar as they are, they each have a distinctive sort of sound:
Miguel: sexy, throwback, baby-making R&B sound
Frank: quiet, thoughtful R&B
The Weeknd: dark, self-flagellating existential R&B
For the songs posed in the OP, I would order them Adorn > Thinking 'Bout You > Wicked Games, but if The Weeknd song was changed to The Morning, my order would definitely be different.
Here's a really good article regarding all three artists and their place among critics -- it's an interesting read:
