For me: Littlefinger, Eddard, Arya, Syrio, Jon, Jaqen, Brienne, Davos, and Beric.

I'm only 2/3 of the way through the first book, but I like Jon, Arya, and Tyrion. Hmmm, I'm not sure I like them so much as look forward to finding out what happens to them in particular.

Tyrion first and foremost. Then Jojen and Meera Reed, Arya and Jamie.

I really despise Littlefinger and Cersei.

My favorites would have to be: Tyrion, Jon Snow, Varys, and (though his appearance is brief) Ser Cortnay Penrose.

After finishing the (first) four books, I still have to say that I like reading about Jon, Arya, and Tyrion the most. I also kept looking forward to more Brienne.

On my second time through the books, I'm discovering that I like Catelyn less and less.

JON SNOW wins by a mile

I was a big Maester Aemon fan.

I also really like Littlefinger for some strange reason. I wish they'd give him some point-of-view chapters.

All of the Starks, but Catelyn.
Also, Tyrion gets my sympathy.

The Hound by far is my favourite, although Bronn and The Red Viper, and Euron Crows-eye, and Dolorous Edd are all a close second.

In order Daenerys Stormborn, Arya Stark, Tyrion Lannister, newly Jaime Lannister, Barristan Selmy, Jon Snow, Samwell Tarly, Varys, The Queen of Thorns,
I have to say that I find Arya and Daenerys to be huge favorites because of their evolution as people as well as growing powers, also Barristan Selmy is always interesting because of his unwavering honor tempered by bitter resentment of the world, Tyrion is just plain fun to watch him struggle to be good when he is so good at being bad, Jaime always was a fun character because he was so one dimensional and almost comical in his evil until recently, Varys has his fingers in everything and everyone, Jon I like but he is too obviously the hero character for my tastes and I think Sam's constant struggle to be brave to be heartening....I could keep on going forever which is why this series is so amazing

Mine would have to be Daenerys, Littlefinger, Tyrion, Jon, Jaime, Arya and the Hound.

Enjoy reading about Jaime, Bronn, and anything to do with the Greyjoy family.

1.Sandor
2.Bronn
3.Littlefinger

don't know why but I also like Cotter Pyke (commander of the eastwatch -by-the-sea)

Jaime by far. I'm very fond of Jon Snow because I feel like we think the same way...but sometimes I appear as more of a Podrick Payne haha which is why I also like him too.

Oh...and in a way...I feel very sorry for Theon Greyjoy. I don't really think he's a bad guy...he's just had a shitty father haha

Totally Jon Snow, dany, tyrion, eddard for me

i really hated joffrey

Psh. Who doesn't hate Joffrey? I'm glad the queen of thorns took care of him XD I miss Tyrion, and I still love Jaime...sometimes I wish I had a great grandfather like maester Aemon too haha

Oh and has anybody seen the HBO character cast? The kid who got the Joffrey role looks way to young. Catelyn and Cersei need to switch parts, and Sansa is supposed to have auburn hair...the actress that is going to play her is a total blonde. Arya, Bran, and Jon are all good. Jaime too. The guy that's going to play Robb looks way to old. Peter...something plays Tyrion. I can't remember his last name, but he's good for the role. Danny got replaced by a British girl that suits the part better than Tamzin Merchant (she's way to old). And lastly, Sean Bean as Eddard stark! FUCKING PERFECT.

Most of the characters are interesting to read about but my favourites are:
1. Jon Snow
2. Jaime Lannister
3. Tyrion
4. Tie between Arya and Littlefinger

1. Arya Stark
2. Jon Snow
3. Tyrion Lannister

I'm a big fun of the Stark family and not so popular characters of A Song of Ice and Fire:
1. Bran Stark
2. Catelyn Stark
3. Eddard Stark

1.Tyrion and Cersei
2.Arya Stark
3.Daenerys Stormborn
5.Robb Stark
6.Jon Snow
7.Samwell Tarly xD
Hmm....and Maester Aemon too.

1.Jaime Lannister
2.Arya Stark
3.Jon Snow
4.Davos Seaworth
5.Asha Greyjoy
6.Victarion Greyjoy

Jaime Lannister is my favourite. Ramsey Bolton I despise most.

1. Daenerys
2. Jon Snow
3. Arya
4. Bran
5. Sansa

I'm only on A Storm of Swords and I've given myself some spoilers by reading this "I miss Tyrion" somebody said, that makes me said I hope he doesn't get killed off!
My favourites are, Tyrion, Dany and Jon.
That's not in order though because every day i find myself saying "Ok this one is my favourite then the next day i'm like no this one"!

George RR Martin makes it very hard to pick just one as a favourite I think, I don't care how long it takes him to finish them he is amazing.

I just begun A Feast For Crows and wow... well... should I list everyone I liked, or just the more or less main characters? Whatever...

Arya,
Tyrion,
Varys,
Lord Beric,
Mance Ryader,
Khal Drogo,
Oberyn Martell
(my four main crushes so far),
Davos.

Minor characters I really liked: Gilly, Old Nan, Queen of Thorns, Dalla, Grenn, Pyp, Dolorous Edd, Tom O' Sevens, Thoros of Myr, Syrio Forel, Vargo Hoat, Tormund Giantsbane, Donal Noye, Hot Pie.

Deceased characters whose personality we mainly just imagine: Rhaegar Targaryen, Rhaenys, Arthur Dayne, Brandon Stark (he opened Littlefinger, that's enough to like him)

I really like all the characters! I agree with pretty much all these lists! There are very little characters who I dislike! But my Top 5 are:
Tyrion Lannister
The Hound
Arya Stark
Jaime Lannister
Littlefinger

M favs: Tyrion
Jaime
Stannis
Euron
Dany

My favorites are Jon, Jaime, Arya, Asha, Littlefinger, Brienne, Daenerys, Robb, Tyrion, Podrik. Yeah, I think that's it, but maybe there are more. Oh, and Samwell, Coldhands and Jaqen H'ghar too. Oh, and Lady Stoneheart, and Bran, and Meera and Jojen. Oh, and Loras too, and Cersei and the Red Viper. Hope I didn't forget any.

The ones I despise the most are Ramsay, the Leech Lord, Joffrey, Freys (Lord Walder Frey most of all), Sansa (though she's getting better), guess that's it?

So what you mean is you like her better abused and abandoning her ideals, lol. I also love how many of you are ranking an innocent little girl with literal rapists and murderers. This fandom is so embarrassing.

Catelyn
Sam
Bran
Brienne
Cersei
Elia Martell
Ned
Daenerys

Honorable mentions: Osha, Myrcella, Tommen, the Reeds, Aemon, Lewin.

Least favorite:

Arya (I don't hate her but she is so boring and was a brat in book 1)
Tyrion (compelling chapters but he's a rapist, child molester, and misogynist)
Ygritte (don't care for the character tropes she represents, like Arya)
Olenna and Margaery
