ONE OF MY ALL TIME FAVORITE SHOWS! I've never seen Game of Thrones and honestly I don't really want to because it doesn't seem like my thing.

Game of Thrones is good--though I'm not a huge huge fan. But Once is the best.

From what I've heard about Once Upon a Time, it seems a bit ridiculous. I have nothing against the fandom, however. If they like OUaT, they can go ahead and fangirl/boy over it.
As for Game of Thrones, I've never seen it. I have heard the gist of the show, though. Death and sex. Also dragons.

This is my third-favorite show of all time! Honestly, Game of Thrones could probably be summed up in three words: death, sex, and dragons. I've never seen it, though, and I have no desire to.

One of my favorite shows atm. <3 Have yet to watch GoT, don't know if I'll get into it.

I've never seen Game of Thrones, but Once Upon a Time is one my favorite shows.

BY FAR, better universe, better characters, better plot, better music, better cast...
I loved the first season of OUAT , but after that it became a total mess, and the acting can be extremely cringeworthy

@hatelarxene: I think it's hypocritical to say "hurr durr game of thrones is just dragons sEx and death" while you've never actually seen it
