Ron Hermione because there is a balance in their relationship Hermione just because Ron is her boyfriend doesn't mean she is going to let him be in control of the relationship she is the brains and she is independent Ron also does not try to control Hermione and tell her who to see and what to do and he let's her defend herself and be involved in battles In Edward and Bella's "relationship" Bella is weak and hides behind Edward all the time and let's him be in control Edward is controlling and doesn't let Bella be involved in anything he basically treated her like a child to me Edward and Bella did not Amore each other they got into a relationship based on Lust and Looks not personality never did Bella truly mostra how much she loved Edward and if she did it was spoiled because she always was talking about how incredibly god like he was AND Edward I believe got with Bella because he couldn't read her mind and she smelled nice I know some may disagree but this is the way I saw it
Ron and Hermione beacuse we have been waiting for them to get together through 6 libri before they finally get together in the 7th. Edward and Bella make a good couple because they are boring but the series revolves around them so it doesn't make a big impact and it doesn't make te route for them to be together because she made it obvious since the first time youe see Edward. While Ron and Hermione argue and have falling outs because they actually Amore each other.
They make each other stronger. They push each other to be better. And most importantly, they lean on each other, but they don't depend on each other. Hermione can get on perfectly fine without Ron, but when she needs his help, she's willing to ask. The same goes for Ron. He has survived without her, but in the end, he would rather have her around.
