Here's everyone's favorite (not to take sides, I'm simply stating the facts)! Rem 

First an overview!
 
 
 
As the younger of the twins, Rem is captured in a kneeling pose
Again, the maid costume is a-ok from every angle, very impressive!
 
The blushes and that innocent look in her expression are what distinguished her character from Ram (what? the hair color, and bust size? )
This figure nailed this difference in my opinion.
You really need to look at these ornaments with a pair magnifying glasses!
These fingers are frail and kawaii, I just can't help but feel sorry for her
All in all, this figure carries all the good traits from Ram at the same time also accurately exhibited the different character traits through the nuances in gestures and expressions (what hair color? what bust size? ) 
 
 
...and of course, you need to display her with Rem, best girl or not, they belong together!
