Luna of course. xD

Cadance of course. ^^

Twilight of course!

The answer is yes.

Twi

This one is not that hard to tell.  

Glimmy is cuter

Gee… That’s a tough one.

@CyanLightning
 
How dare you to have a different opinion of an objective and obviously not subjective thing!? I think I know what’s truly heresy here
 

Discord obvisouly :D

hate to say it, but Glimmy Glams.

Twilight hooves down

@TheAnonShy  
The most recent episode, she is significantly taller than Starlight when they are walking together. Nearly an entire horn-height.

@TheAnonShy  
I kinda like Twi’s alicorn model :P

@TheAnonShy  
I’ve always had an issue with Cadance’s model in particular. Girl needs to eat more.

@Ihhh
 
…Not really.
 
Since Twilight became an alicorn, the shape of her body has changed a bit, becoming even more noticeable in the further seasons. She’s now bigger both her chest and horn, as well with height.

^{And I personally like more the unicorn model than alicorn}
 
@ChuymaruZ
 
*like most ponies

@ChuymaruZ  

 
This^

@Ihhh  
like everypony

They have the exact same character model.

@Deon Miller  
image is broken.

Pfft, to choose? Why not both if I can combine them?
 

 
Problem solved

Even Glimmer herself cannot resist the power of Twilight’s cuteness.  

@Amethyst_Crystal  
Starlight doesn’t like equality when applied to herself…

How about ‘equally cute’.
