Better partner for Edward?

Okay so I've seen all the movies (haven't read the books as I struggle with concentration but I would love to) and I've always kind of wondered if any other vampires would have been a better fit for Edward instead of Bella.

I saw a instagram the other day which got me thinking so pretty much (according to the post) Edward thought Bella was pretty unremarkable when he saw her in other people's thoughts until he meets her blah blah but in a book he like goes on and on about one of the vampires in the Irish coven, Siobhan.

So I did some looking around and I feel like Maggie might be a good pairing with Edward, she's righteous, headstrong and strongly believes in justice which I for some reason think Edward would like.

No hate on Bella at all. Just weird autistic thoughts that I can't get out of my head.
Please let me know your pairings?
