It was a tie between DT/SS and Gilda. I finally landed on Gilda, she was MUCH more of a jerk.

I HATE Gilda and Diamond Tiara, but I hate children more. Don't judge me. :P

I dislike Angel with great intensity. :D

The biggest bitches ever.

Let me explain why I chose those two, and tell why I didn't choose any of the others:

DT and SS: They're always feeling that they are on top of every other young pony who has no cutie mark. Despite Diamond Tiara being the more sadistic filly, the two are no dynamic duo.

Now for the ones I didn't choose:

Gilda: She is a jackass, that's true. However, even though she pretends to be friendly, the hatred towards her will not go as far as the two fillies.

Angel: Yes, he's demanding and rude, but he still has a sense of respect.

Iron Will: He is quite the brute, and his assertiveness routines may be too effective because he forces his routines down their throats. However, his power is too easily put down.

Owlowiscious: Nobody understands him. However, he's a loyal pet and would do anything to help out.

At least Diamond Tiara was good at singing. I don't like Angel much either though.

I'll tell why I hate these characters

#6: A Mary Sue
#7: A bully who I blame for everything in "Putting your Hoof Down"
#8: A jerk to his owner
#9: Horrid Bullies
#10: A jerk

First off... these two were only #9 on your list? The buck?
Second... Oh, where the hay do I begin with these walking piles of horseapples? I only had a mild distaste for them at first, and even thought I would tolerate them after One Bad Apple(the reason being the two actually welcomed a blank flank into their clique, but didn't realize it). And then Flight To The Finish happened. Scootagate was born(Will she/won't she fly). And I instantly divebombed them into the tier from hell: Irredeemable. The only time a slide like that ever happened in my lifetime was with Spongebob. (Fuck you, Nickelodeon.) It takes a lot to make a slide almost like what happened with the stock market earlier today(more precisely, around 1:30 PM) happen for a character. These two, or more specifically, Diamond Tiara herself, broke me in that regard. The moment DT used ableism against Scootaloo, was when Tartarus reserved a spot for the pony with the tiara on her head and flank(The latter being her cutie mark). When Scootaloo flies(if she does), the world will cheer like a Kansas City Chiefs stadium jampacked wih fans after a last-second victory. And when the CMC all get their cutie marks, it will be the ultimate "Buck You" to Diamond Tiara. I eagerly await the day.

Well, I assure, that I hate every single character on this list. But, Gilda is the worst on this spectrum, as she is annoying with her speaking pattern, and is so much of a jerk that I can't stand. Sure, Owlicious is an unlikable mary sue, Iron Will is an a****le, Angel is a spoiled brat, and Diamond Tiara is a b***h, but Gilda is just the worst in my opinion

I LUV dt amd ss

I hate DT/SS they are such little brats! Plus, the owl isn't mean :i

How dare they make fun of the Cutie Mark Crusaders.

Though Diamond Tiara and Silver Spoon are bullies I really hate Gila for 1. Trying to keep Pinkie Pie away from my favorite pony Rainbow Dash, 2. Making the adorable Fluttershy cry (That has to be her worst offence, and 3. Losing her temper in front of everybody.
