You mean as in boyfriends for her? I think that Sam was the most suitable for her because he really loved her, to the point that he gave her the ring and he told her about his problems when he had nowhere to live, so he basically trusts her.
Also, I will go all femslash shipper here & say Rachel. She always seems to bring out an emotion out of Quinn (both good and bad) and I like that about them. Also, from all the Glee club, Rachel was the only one who always tried to help her when she was really in need.
Sam is the only guy who doesnt cheat on her :D and Quinn was the first person to come to Sam when he had problem with new school and when his family needed some help .... So bad , no più Fabrevans now
PUCK! A million times Puck! I Amore them, they are my OTP. I was dying all last season due to the attack of Fuinn and Fuinn 2.0 aka Suinn. They both have their moments but...they got nothing on Quick. Puck really loves her,and I don't think Quinn ever really got over him. He makes her into a decent human being, he makes her feel SOMETHING besides the need to be popolare and pretty and she brings out the best in him while still keeping him true to his bad boy self.
I think Jacob Ben Israel detto that Quinn "dumped" Puck. It was più like a Quinn just completely ignored him out of nowhere instead of actually ever saying, "Yeah, ixnay on the relationship thing."
